| 1 | Behaviors and kinetics of toluene adsorption-desorption on activated carbons with varying pore structure显示文摘This work was undertaken to investigate the behaviors and kinetics of toluene adsorption and desorption on activated carbons with varying pore structure. Five kinds of activated carbon from different raw materials were selected. Adsorption isotherms and breakthrough curves for toluene were measured. Langmuir and Freundlich equations were fitted to the equilibrium data, and the Freundlich equation was more suitable for simulating toluene adsorption. The process consisted of monolayer, multilayer and partial active site adsorption types. The effect of the pore structure of the activated carbons on toluene adsorption capacity was investigated. The quasi-first-order model was more suitable for describing the process than the quasi-second-order model. The adsorption data was also modeled by the internal particle diffusion model and it was found that the adsorption process could be divided into three stages. In the external surface adsorption process, the rate depended on the specific surface area. During the particle diffusion stage, pore structure and volume were the main factors affecting adsorption rate. In the final equilibrium stage, the rate was determined by the ratio of meso-and macro-pores to total pore volume. The rate over the whole adsorption process was dominated by the toluene concentration. The desorption behavior of toluene on activated carbons was investigated,and the process was divided into heat and mass transfer parts corresponding to emission and diffusion mechanisms, respectively. Physical adsorption played the main role during the adsorption process. | Xi Yang Honghong Yi Xiaolong Tang Shunzheng Zhao Zhongyu Yang Yueqiang Ma Tiecheng Feng Xiaoxu Cui | 2018 | Journal of Environmental Sciences2018,30,5: | 28 |

| 3 | Plant salt tolerance and Na^+ sensing and transport显示文摘Salinity is a global challenge to agricultural production. Understanding Na^+ sensing and transport in plants under salt stress will be of benefit for breeding robustly salt-tolerant crop species. In this review, first, possible salt stress sensor candidates and the root meristem zone as a tissue harboring salt stress-sensing components are proposed. Then,the importance of Na^+ exclusion and vacuolar Na^+ sequestration in plant overall salt tolerance is highlighted. Other Na^+ regulation processes, including xylem Na^+ loading and unloading, phloem Na^+ recirculation, and Na^+ secretion, are discussed and summarized.Along with a summary of Na^+ transporters and channels, the molecular regulation of Na^+ transporters and channels in response to salt stress is discussed. Finally, some largely neglected issues in plant salt stress tolerance, including Na^+ concentration in cytosol and the role of Na^+ as a nutrient, are reviewed and discussed. | Honghong Wu | 2018 | The Crop Journal2018,6,3: | 20 |
| 4 | The poisoning and regeneration effect of alkali metals deposed over commercial V_2O_5-WO_3/TiO_2 catalysts on SCR of NO by NH_3显示文摘In this study,commercial V2O5-WO3/TiO2catalysts were deactivated by loading with alkali metals(K and Na).These catalysts were then regenerated by washing with either deionized water or 0.5 mol/L H2SO4(through the ultrasonic-assisted method).The samples used in this research were characterized by NH3-temperature programmed desorption(TPD),and X-ray photoelectron spectroscopy(XPS).Results showed that Na2O and K2O doping can poison the V2O5-WO3/TiO2catalyst and that the poisoning effect of Na2O was stronger than that of K2O.However,the Na2O-loaded sample was easier to regenerate than the K2O-loaded sample.The surfaces of catalysts can be sulfated by washing with dilute sulfuric acid because strong acid sites adhere to the catalyst surface.SO42-could also promote catalyst activity.As indicated by the NH3-TPD findings,the deposition of Na2O and K2O could also reduce the amount of desorbed ammonia and destabilize the acid sites,especially strong chemisorption sites.XPS results revealed that catalysts were deactivated by the decrease in the concentration of chemisorbed oxygen[the Oa/(Oα+Oβ)ratio].In the Na2O-doped catalyst,much chemisorbed oxygen was lost(from 28.8%to10.6%).However,the decrease in the Oa/(Oα+Oβ)ratio was less significant in the K2O-doped catalyst(from28.8%to 23.5%).Nonetheless,the binding energies of O1s broadened with respect to both high and low energy.In particular,the binding energy of chemisorbed oxygen increased from 531.5 to 531.8 eV. | Fengyu Gao Xiaolong Tang Honghong Yi Shunzheng Zhao Tongtong Zhang Dong Li Ding Ma | 2014 | Chinese Science Bulletin2014,59,31: | 19 |
| 5 | Effects of ammonium exchange and Si/Al ratio on the conversion of methanol to propylene over a novel and large partical size ZSM-5显示文摘One type of ZSM-5 zeolite with large partical size was prepared and characterized by XRD, SEM, N2 adsorption-desorption, XRF, Py-IR and NH3-TPD techniques. Effects of ammonium exchange and SiO2/Al2O3 molar ratios on the reaction of methanol to propylene (MTP) over Na-ZSM-5 and H-ZSM-5 zeolites have been studied in a fixed-bed flow reactor under the operating conditions of T = 500 °C, P = 1 atm, and WHSV = 6 h-1. Ammonium exchange led to a rapid decrease in Na content for Na-ZSM-5 zeolite. The reaction results indicated that Na-ZSM-5 and H-ZSM-5 with different SiO2/Al2O3 molar ratios all exhibited high activity for methanol conversion. Ammonium exchange and the decreased SiO2/Al2O3 molar ratio of ZSM-5 zeolite led to an increase both in strong acid sites and weak acid sites. Na-ZSM-5 with high SiO2/Al2O3 molar ratio was favorable for the formation of propylene. The highest propylene selectivity (45.9%) was obtained over Na-ZSM-5 zeolite catalyst with SiO2/Al2O3 molar ratio of 220. | Ruchao Wei Chunyi Li Chaohe Yang Honghong Shan | 2011 | Journal of Natural Gas Chemistry2011,20,3: | 12 |
| 6 | Formation of active oxygen species on single-atom Pt catalyst and promoted catalytic oxidation of toluene显示文摘Catalytic oxidation of toluene over noble metal catalysts is a representative reaction for elimination of volatile organic compounds(VOCs).However,to fully understand the activation of molecular oxygen and the role of active oxygen species generated in this reaction is still a challenging target.Herein,MgO nanosheets and single-atom Pt loaded MgO(Pt SA/MgO)nanosheets were synthesized and used as catalysts in toluene oxidation.The activation process of molecular oxygen and oxidation performance on the two catalysts were contrastively investigated.The Pt SA/MgO exhibited significantly enhanced catalytic activity compared to MgO.The oxygen vacancies can be easily generated on the Pt SA/MgO surface,which facilitate the activation of molecular oxygen and the formation of active oxygen species.Based on the experimental data and theoretical calculations,an active oxygen species promoted oxidation mechanism for toluene was proposed.In the presence of H2O,the molecular oxygen is more favorable to be dissociated to generate•OH on the oxygen vacancies of the Pt SA/MgO surface,which is the dominant active oxygen species.We anticipate that this work may shed light on further investigation of t10.1007/s12274-020-2765-1he oxidation mechanism of toluene and other VOCs over noble metal catalysts. | Shunzheng Zhao Yanfeng Wen Xijun Liu Xianyun Pen Fang Lü Fengyu Gao Xizhou Xie Chengcheng Du Honghong Yi Dongjuan Kang Xiaolong Tang | 2020 | Nano Research2020,13,6: | 12 |
| 7 | Hierarchical ZSM-11 with intergrowth structures:Synthesis,characterization and catalytic properties显示文摘Hierarchical ZSM-11 microspheres with intercrystalline mesoporous properties and rod-like crystals intergrowth morphology have been synthesized using a spot of tetrabutylammonium as a single template.XRD,FTIR,SEM,TEM and N2 adsorption analysis revealed that each individual particle was composed of nanosized rod crystals inserting each other and the intercrystalline voids existing among rods gave a significant mesopore size distribution.Steam treatment result demonstrated the excellent hydrothermal stability of samples.Various crystallization modes including constant temperature crystallization (one-stage crystallization) and two-stage temperature-varying crystallization with different 1st stage durations were investigated.The results suggested that the crystallization modes were mainly responsible for the adjustable particle size and textural properties of samples while the small amount of tetrabutylammonium bromide was mainly used to direct the formation of both ZSM-11 framework and its intergrowth morphology.Furthermore,the performance of optimal ZSM-11 as an active component for the catalytic pyrolysis of heavy oil was also investigated.Compared with the commercial pyrolysis catalyst,the hierarchical ZSM-11 catalyst exhibited a high selectivity to desired products(LPG+gasoline+diesel),as well as a much lower dry gas and coke yield,plus a high selectivity and yield of light olefins(C=3 C=4)and very poor selectivity to benzene.Therefore,fully open micropore-mesopore connectivity would make such hierarchically porous ZSM-11 zeolites very attractive for applications in clean petrochemical catalysis field. | Qingjun Yu Chaoyue Cui Qiang Zhang Jing Chen Yang Li Jinpeng Sun Chunyi Li Qiukai Cui Chaohe Yang Honghong Shan | 2013 | Journal of Energy Chemistry2013,22,5: | 10 |

| 10 | A high-surface-area silicoaluminophosphate material rich in Brnsted acid sites as a matrix in catalytic cracking显示文摘A transparent gel-like mesoporous silicoaluminophosphate material (SAP) with a Si/Al molar ratio of 20 was synthesized by hydrothermal method. The physicochemical features of SAP were characterized by XRD, XRF, BET, SEM and FT-IR spectroscopy of pyridine adsorption techniques. The results indicated that incorporation of phosphorus (P) into aluminasilica system altered the basic textural characteristics of aluminasilica. Especially after hydrothermal treatment, the material with large special surface area (up to 492 m 2 /g) exhibited a good performance on hydrothermal stability. Moreover, the phosphorus modifier can not only increase the amount of Bro¨nsted acidic sites (up to 48.44 μmol/g) and the percentage of weak acidic sites in total acidic sites, but also regulate the acid type, such as the ratio of B/L (Bro¨nsted acid/Lewis acid) increases to 1.15. The performances of samples as matrices for the catalytic cracking of heavy vacuum gas oil (VGO) were investigated. At 520 C, the catalysts showed much higher gasoline and diesel oil yields achieving to 45.59 wt% and 19.20 wt%, respectively, and lower coke selectivity (2.86%) than conventional FCC matrices, such as kaolin and amorphous silica-alumina. | Shaoiun Xu Qiang Zhang Zhaoxuan Feng Xiaojing Meng Tongyu Zhao Chunyi Li Chaohe Yang Honghong Shan | 2012 | Journal of Natural Gas Chemistry2012,21,6: | 8 |
| 11 | Graphitic carbon nitride/biochar composite synthesized by a facile ball-milling method for the adsorption and photocatalytic degradation of enrofloxacin显示文摘In order to enhance the removal performance of graphitic carbon nitride(g-C_(3)N_(4)) on organic pollutant, a simultaneous process of adsorption and photocatalysis was achieved via the compounding of biochar and g-C_(3)N_(4). In this study, g-C_(3)N_(4) was obtained by a condensation reaction of melamine at 550 °C. Then the g-C_(3)N_(4)/biochar composites were synthesized by ball milling biochar and g-C_(3)N_(4) together, which was considered as a simple, economical, and green strategy. The characterization of resulting g-C_(3)N_(4)/biochar suggested that biochar and g-C_(3)N_(4) achieved effective linkage. The adsorption and photocatalytic performance of the composites were evaluated with enrofloxacin(EFA) as a model pollutant. The result showed that all the g-C_(3)N_(4)/biochar composites displayed higher adsorption and photocatalytic performance to EFA than that of pure g-C_(3)N_(4). The 50% g-C_(3)N_(4)/biochar performed best and removed 45.2% and 81.1% of EFA(10 mg/L) under darkness and light with a dosage of 1 mg/mL, while g-C_(3)N_(4) were 19.0% and 27.3%, respectively. Besides, 50% g-C_(3)N_(4)/biochar showed the highest total organic carbon(TOC) removal efficiency(65.9%). Radical trapping experiments suggested that superoxide radical( ·O_(2)^(-)) and hole(h~+) were the main active species in the photocatalytic process. After 4 cycles, the composite still exhibited activity for catalytic removal of EFA. | Yao Xiao Honghong Lyu Chengliang Yang Beibei Zhao Lan Wang Jingchun Tang | 2021 | Journal of Environmental Sciences2021,33,5: | 8 |
| 12 | Application of AERMOD on near future air quality simulation under the latest national emission control policy of China: A case study on an industrial city显示文摘Air quality model can be an adequate tool for future air quality prediction, also atmospheric observations supporting and emission control strategies responders. The influence of emission control policy (emission reduction targets in the national 'China's 12th Five-Year Plan (2011-2015)') on the air quality in the near future over an important industrial city of China, Xuanwei in Yunnan Province, was studied by applying the AERMOD modeling system. First, our analysis demonstrated that the AERMOD modeling system could be used in the air quality simulation in the near future for SO2 and NOx under average meteorology but not for PM10. Second, after evaluating the simulation results in 2008 and 2015, ambient concentration of SO2, NOx and PM10 (only 2008) were all centered in the middle of simulation area where the emission sources concentrated, and it is probably because the air pollutions were source oriented. Last but not least, a better air quality condition will happen under the hypothesis that the average meteorological data can be used in near future simulation. However, there are still heavy polluted areas where ambient concentrations will exceed the air quality standard in near future. In spatial allocation, reduction effect of SO2 is more significant than NOx in 2015 as the contribution of SO2 from industry is more than NOx. These results inspired the regulatory applications of AERMOD modeling system in evaluating environmental pollutant control | Jieyun Ma Honghong Yi Xiaolong Tang Yan Zhang Ying Xiang Li Pu | 2013 | Journal of Environmental Sciences2013,25,8: | 8 |
| 13 | Reversible Histone H2B Monoubiquitination Fine-Tunes Abscisic Acid Signaling and Drought Response in Rice显示文摘Histone H2B monoubiquitination (H2Bub1) plays important roles in several physiological and developmental processes, but its roles in the regulation of plant stress responses remain elusive. Here, we report that H2Bub1 is crucially involved in abscisic acid (ABA) signaling and drought response in rice. We found that rice HISTONE MONOUBIQUITINATION2 (OsHUB2), an E3 ligase for H2Bub1, in teracted with OsbZIP46, a key transcription factor regulating ABA signaling and drought response in rice. Genetic analyses suggest that OsHUB2, upregulated by drought and ABA, positively modulates ABA sensitivity and drought resistance. The H2Bub1 levels were in creased in the target genes of OsbZIP46 under the drought stress and ABA treat- merits, which were positively correlated with their increased expression levels. Interestingly, MODD, a reported suppressor of ABA signaling and drought resistance by mediating OsbZIP46 deactivation and degradation, could reduce the H2Bub1 levels in the target genes of OsbZIP46 by recruiting a putative deubiquitinase OsOTLD1 . Suppression of OsOTLD1in vivo resulted in increased H2Bub1 levels and expression of OsbZIP46 target genes. Collectively, these fin dings established an elaborate mecha nism of histone monoubiquitination in the fine-turning of ABA signaling and drought response by balancing H2Bub1 deposition and removal. | Siqi Ma Ning Tang Xu Li Yongjun Xie Denghao Xiang Jie Fu Jianqiang Shen Jun Yang Haifu Tu Xianghua Li Honghong Hu Lizhong Xiong | 2019 | Molecular Plant2019,12,2: | 7 |
| 14 | Solvent-Free Synthesis of Ultrafine Tungsten Carbide Nanoparticles-Decorated Carbon Nanosheets for Microwave Absorption显示文摘Carbides/carbon composites are emerging as a new kind of binary dielectric systems with good microwave absorption performance.Herein,we obtain a series of tungsten carbide/carbon composites through a simple solvent-free strategy,where the solid mixture of dicyandiamide(DCA)and ammonium metatungstate(AM)is employed as the precursor.Ultrafine cubic WC1-x nanoparticles(3-4 nm)are in situ generated and uniformly dispersed on carbon nanosheets.This configuration overcomes some disadvantages of conventional carbides/carbon composites and is greatly helpful for electromagnetic dissipation.It is found that the weight ratio of DCA to AM can regulate chemical composition of these composites,while less impact on the average size of WC1-x nanoparticles.With the increase in carbon nanosheets,the relative complex permittivity and dielectric loss ability are constantly enhanced through conductive loss and polarization relaxation.The different dielectric properties endow these composites with distinguishable attenuation ability and impedance matching.When DCA/AM weight ratio is 6.0,the optimized composite can produce good microwave absorption performance,whose strongest reflection loss intensity reaches up to-55.6 dB at 17.5 GHz and qualified absorption bandwidth covers 3.6-18.0 GHz by manipulating the thickness from 1.0 to 5.0 mm.Such a performance is superior to many conventional carbides/carbon composites. | Yunlong Lian Binhua Han Dawei Liu Yahui Wang Honghong Zhao Ping Xu Xijiang Han Yunchen Du | 2020 | Nano-Micro Letters2020,12,11: | 7 |
| 15 | Simultaneous catalytic hydrolysis of carbonyl sulfide and carbon disulfide over Al_2O_3-K/CAC catalyst at low temperature显示文摘In this work, a series of coal-based active carbon(CAC) catalysts loaded by Al2O3were prepared by sol-gel method and used for the simultaneous catalytic hydrolysis of carbonyl sulfide(COS) and carbon disulfide(CS2) at relatively low temperatures of 30-70 ℃. The influences of calcinations temperatures and operation conditions such as: reaction temperature, O2concentration, gas hourly space velocity(GHSV) and relative humidity(RH) were also discussed respectively. The results showed that catalysts with 5.0 wt% Al2O3calcined at 300 ℃ had superior activity for the simultaneous catalytic hydrolysis of COS and CS2. When the reaction temperature was above 50 ℃, catalytic hydrolysis activity of COS could be enhanced but that of CS2was inhibited. Too high RH could make the catalytic hydrolysis activities of COS and CS2decrease. A small amount of O2introduction could enhance the simultaneous catalytic hydrolysis activities of COS and CS2. | Xin Sun Ping Ning Xiaolong Tang Honghong Yi Kai Li Dan He Xianmang Xu Bin Huang Ruiyun Lai | 2014 | Journal of Energy Chemistry2014,23,2: | 7 |
| 16 | K^+ retention in leaf mesophyll, an overlooked component of salinity tolerance mechanism:A case study for barley显示文摘Plant salinity tolerance is a physiologically complex trait, with numerous mechanisms contributing to it. In this work,we show that the ability of leaf mesophyll to retain Kt represents an important and essentially overlooked component of a salinity tolerance mechanism. The strong positive correlation between mesophyll Ktretention ability under saline conditions(quantified by the magnitude of Na Cl-induced Kt efflux from mesophyll) and the overall salinity tolerance(relative fresh weight and/or survival or damage under salinity stress) was found while screening 46 barley(Hordeum vulgare L.) genotypes contrasting in their salinity tolerance. Genotypes with intrinsically higher leaf Ktcontent under control conditions were found to possess better Ktretention ability under salinity and, hence, overall higher tolerance. Contrary to previous reports for barley roots, Ktretention in mesophyll was not associated with an increased Ht-pumping in tolerant varieties but instead correlated negatively with this trait. These findingsare explained by the fact that increased Htextrusion may be needed to charge balance the activity and provide the driving force for the high affinity HAK/KUP Kttransporters required to restore cytosolic Kthomeostasis in salt-sensitive genotypes. | Honghong Wu Min Zhu Lana Shabala Meixue Zhou Sergey Shabala | 2015 | Journal of Integrative Plant Biology2015,57,2: | 7 |

| 18 | Composition Optimization and Microstructure Design in MOFs-Derived Magnetic Carbon-Based Microwave Absorbers:A Review显示文摘Magnetic carbon-based composites are the most attractive candidates for electromagnetic(EM)absorption because they can terminate the propagation of surplus EM waves in space by interacting with both electric and magnetic branches.Metal-organic frameworks(MOFs)have demonstrated their great potential as sacrificing precursors of magnetic metals/carbon composites,because they provide a good platform to achieve high dispersion of magnetic nanoparticles in carbon matrix.Nevertheless,the chemical composition and microstructure of these composites are always highly dependent on their precursors and cannot promise an optimal EM state favorable for EM absorption,which more or less discount the superiority of MOFs-derived strategy.It is hence of great importance to develop some accompanied methods that can regulate EM properties of MOFs-derived magnetic carbon-based composites e ectively.This review comprehensively introduces recent advancements on EM absorption enhancement in MOFs-derived magnetic carbon-based composites and some available strategies therein.In addition,some challenges and prospects are also proposed to indicate the pending issues on performance breakthrough and mechanism exploration in the related field. | Honghong Zhao Fengyuan Wang Liru Cui Xianzhu Xu Xijiang Han Yunchen Du | 2021 | Nano-Micro Letters2021,13,12: | 6 |
| 19 | Synergistic effect of W and P on ZSM-5 and its catalytic performance in the cracking of heavy oil显示文摘In order to develop the conversion of heavy oil with a high yield of propylene in the catalytic cracking process, ZSM-5 zeolite was modified by tungsten and phosphorus, which was proved to be an effective method. Characterization results show that the improvement of catalytic performance could be correlated to the interaction of phosphorus and tungsten species on ZSM-5. P inhibited the aggregation of tungsten species on ZSM-5 and was conductive to convert the tungsten species with octahedral coordination into tetrahedral coordination. And this ultimately led to that more acid sites were reserved after hydrothermal treatment in the tungsten and phosphorus co-modified ZSM-5 catalyst.Phosphorus species played an important role to restrain the dehydrogenation activity of tungsten. In addition, a model reflecting the interaction between tungsten species and ZSM-5 framework was proposed. | Dongmin Han Nannan Sun Jianwei Liu Chunyi Li Honghong Shan Chaohe Yang | 2014 | Journal of Energy Chemistry2014,23,4: | 5 |
| 20 | Advances in core–shell engineering of carbon-based composites for electromagnetic wave absorption显示文摘Electromagnetic(EM)absorption is paving the way to overcome the challenges related to conventional shielding strategy against EM pollution through sustainable energy dissipation.As characteristic functional media that can interact with electric or magnetic field branch,EM wave absorption materials(EWAMs)have received extensive attention and realized considerable development in the past two decades,where carbon-based composites are always considered as promising candidates for high-performance EMAWs due to their synergetic loss mechanism as well as diversified composition and microstructure design.Recent progress indicates that there is more and more interest in the fabrication of carbon-based composites with unique core–shell configuration.On one hand,core–shell configuration usually ensures good chemical homogeneity of final products and provides some positive protections for the components with susceptibility to corrosion,on the other hand,it creates enough heterogeneous interfaces between different EM components,which may bring enhanced polarization effect and intensify the consumption of EM energy.In this review,we firstly introduce EM wave absorption theory,and then highlight the advances of core–shell engineering in carbonbased composites in terms of built-in carbon cores and built-out carbon shells.Moreover,we also show some special core–shell carbon-based composites,including carbon/carbon composites,assembled composites,and decorated composites.After analyzing EM absorption performance of some representative composites,we further propose some challenges and perspectives on the development of core–shell carbon-based composites. | Lixue Gai Honghong Zhao Fengyuan Wang Pan Wang Yonglei Liu Xijiang Han Yunchen Du | 2022 | Nano Research2022,15,10: | 5 |
