| 1 | FeCo alloy@N-doped graphitized carbon as an efficient cocatalyst for enhanced photocatalytic H2 evolution by inducing accelerated charge transfer显示文摘Cocatalysts play important roles in improving the activity and stability of most photocatalysts.It is of great significance to develop economical,efficient and stable cocatalysts.Herein,using Na2CoFe(CN)6 complex as precursor,a novel noble-metal-free FeCo@NGC cocatalyst(nano-FeCo alloy@N-doped graphitized carbon) is fabricated by a simple pyrolysis method.Coupling with g-C3 N4, the optimal FeCo@NGC/g-C3N4 receives a boosted visible light driven photocatalytic H2 evolution rate of 42.2 μmol h-1, which is even higher than that of 1.0 wt% Pt modified g-C3N4 photocatalyst.Based on the results of density functional theory(DFT) calculations and practical experiment measurements,such outstanding photocatalytic performance of FeCo@NGC/g-C3N4 is mainly attributed to two aspects.One is the accelerated charge transfer behavior,induced by a photogene rated electrons secondary transfer performance on the surface of FeCo alloy nanoparticles.The other is related to the adjustment of H adsorption energy(approaching the standard hydrogen electrode potential) by the presence of external NGC thin layer.Both factors play key roles in the H2 evolution reaction.Such outstanding performance highlights an enormous potential of developing noble-metal-free bimetallic nano-alloy as inexpensive and efficient cocatalysts for solar applications. | Sibo Chen Yun Hau Ng Jihai Liao Qiongzhi Gao Siyuan Yang Feng Peng Xinhua Zhong Yueping Fang Shengsen Zhang | 2021 | Journal of Energy Chemistry2021，30，1： | 3 |
| 2 | Enhanced removal of sulfonamide antibiotics from water by phosphogypsum modified biochar composite显示文摘Antibiotic pollution has become a global eco-environmental issue.To reduce sulfonamide antibiotics in water and improve resource utilization of solid wastes,phosphogypsummodified biochar composite(PMBC)was prepared via facile one-step from distillers grains,wood chips,and phosphogypsum.The physicochemical properties of PMBCwere characterized by scanning electron microscope(SEM),Fourier transform infrared spectroscopy(FTIR),Zeta potential,X-ray diffraction(XRD),etc.The influencing factors,adsorption behaviors,and mechanisms of sulfadiazine(SD)and sulfamethazine(SMT)onto PMBC were studied by batch and fixed bed column adsorption experiments.The results showed that the removal rates of SD and SMT increased with the increase of phosphogypsum proportion,while decreased with the increase of solution pH.The maximum adsorption capacities of modified distillers grain and wood chips biochars for SD were 2.98 and 4.18 mg/g,and for SMT were 4.40 and 8.91mg/g,respectively,which was 9.0–22.3 times that of pristine biochar.Fixed bed column results demonstrated that PMBC had good adsorption capacities for SD and SMT.When the solution flow rate was 2.0 mL/min and the dosage of PMBC was 5.0 g,the removal rates of SD and SMT by modified wood chips biochar were both higher than 50%in 4 hr.The main mechanisms of SD and SMT removal by PMBC are hydrogen bonding,π-πdonor-acceptor,electrostatic interaction,and hydrophobic interaction.This study provides an effective method for the removal of antibiotics in water and the resource utilization of phosphogypsum. | Zonghong Jiang Miao Chen Xinqing Lee Qianwei Feng Ning Cheng Xueyang Zhang Shengsen Wang Bing Wang | 2023 | Journal of Environmental Sciences2023，，8： | 2 |

| 4 | Sustainable engineering of TiO_(2)-based advanced oxidation technologies:From photocatalyst to application devices显示文摘In recent years,photocatalysis(PC)and photoelectrocatalysis(PEC)technologies have shown great promise as low-cost,environmentally friendly,and sustainable strategies in addressing the issues of energy shortages and environmental pollution,which has become a research hotspot.Titanium dioxide(TiO_(2))-based PC and PEC are the most promising sustainable technologies for advanced oxidation applications.Due to its inherent characteristics,including high oxidation ability,low price,and stability,TiO_(2)photocatalyst has been widely studied and used in different scales for numerous decades.For practical applications in these areas,the engineering of the photocatalysts and the design of the PC and PEC devices must be both environmentally and economically sustainable.On the one hand,for the engineering of the photocatalysts,the photocatalyst shall be able to deliver the following characteristics,including large specific surface area,high absorption of light,rapid and low-cost separation and regeneration,and high stability.On the other hand,the design of the PC and PEC devices shall facilitate high in energy utilization and catalytic efficiency,and low in building and operational cost.This work covers the reaction mechanism of TiO_(2)-based PC and PEC technologies,sustainable design,and preparation of TiO_(2)photocatalysts as well as sustainable design in PC and PEC devices for wastewater treatment,sensing,and water splitting.Finally,we provide some critical perspectives on the future development of TiO_(2)-based PC and PEC technology. | Meng Zu Xiaosong Zhou Shengsen Zhang Shangshu Qian Dong-Sheng Li Xianhu Liu Shanqing Zhang | 2021 | Journal of Materials Science & Technology2021，，19： | 1 |

| 8 | One-step preparation of a novel graphitic biochar/Cu^(0)/Fe_(3)O_(4) composite using CO_(2)-ambiance pyrolysis to activate peroxydisulfate for dye degradation显示文摘Herein,a one-step co-pyrolysis protocol was adopted for the first time to prepare a novel pyrogenic carbon-Cu^(0)/Fe_(3)O_(4)heteroatoms (FCBC) in CO_(2)ambiance to discern the roles of each component in PDS activation.During co-pyrolysis,CO_(2)catalyzed formation of reducing gases by biomass which facilitated reductive transformation of Fe^(3+)and Cu^(2+)to Cu^(0)and Fe_(3)O_(4),respectively.According to the analysis,the resulting metal (oxide) catalyzed graphitization of biocharand decomposition of volatile substances resulting in an unprecedented surface area (1240 m^(2)/g).The resulting FCBC showed greater structural defects and less electrical impedance.Batch experiments indicated that Rhodamine B (RhB) degradation by FCBC (100%) was superior to Fe_(3)O_(4)(50%) and Cu^(0)/Fe_(3)O_(4)(76.4%) in persulfate (PDS) system,which maintained reasonable efficiency (75.6%-63.6%) within three cycles.The reactive oxygen species (ROS) associated with RhB degradation was identified by an electron paramagnetic resonance and confirmed by scavenging experiments.RhB degradation invoked both(sulfate and dominantly hydroxyl) radical and non-radical (singlet oxygen,^(1)O_(2)) pathways.Regarding FCBC,Cu^(0)can continuously react with Fe^(3+)in Fe_(3)O_(4)to generate larger quantities of Fe^(2+),and both Cu^(0)and Fe^(2+)activated PDS to yield sulfate radicals which was quickly converted to hydroxyl radical.Besides,Cu^(0)/Cu^(2+)could complex with PDS to form a metastable complex,which particularly contributed to1O_(2)generation.These cascade reactions by FCBC were reinforced by carbonyl group of biochar and favorable electron transfer ability.This work highlighted a new approach to prepare a magnetic and environment-benign heterogonous catalyst to remove organic pollutants in water. | Yangfan Yuan Changai Zhang Chenhao Zhao BingWang Xiaozhi Wang Bin Gao Shengsen Wang Jorg Rinklebe | 2023 | Journal of Environmental Sciences2023，，3： | 0 |
| 9 | Photoinduced Cu^(+)/Cu^(2+)interconversion for enhancing energy conversion and storage performances of CuO based Li-ion battery显示文摘Pursuing appropriate photo-active Li-ion storage materials and understanding their basic energy storage/conversion principle are pretty crucial for the rapidly developing photoassisted Li-ion batteries(PA-LIBs).Copper oxide(CuO)is one of the most popular candidates in both LIBs and photocatalysis.While CuO based PA-LIBs have never been reported yet.Herein,one-dimensional(1D)CuO nanowire arrays in situ grown on a three-dimensional(3D)copper foam support were employed as dualfunctional photoanode for both‘solar-to-electricity’and‘electricity-to-chemical’energy conversion in the PA-LIBs.It is found that light energy can be indeed stored and converted into electrical energy through the assembled CuO based PA-LIBs.Without external power source,the photo conversion efficiency of CuO based photocell reaches about 0.34%.Impressively,at a high current density of 4000 m A g^(-1),photoassisted discharge and charge specific capacity of CuO based PA-LIBs respectively receive 64.01%and 60.35%enhancement compared with the net electric charging and discharging process.Mechanism investigation reveals that photogenerated charges from CuO promote the interconversion between Cu^(2+)and Cu^(+)during the discharging/charging process,thus forcing the lithium storage reaction more completely and increasing the specific capacity of the PA-LIBs.This work can provide a general principle for the development of other high-efficient semiconductor-based PA-LIBs. | Qiuman Zhang Meng Wei Qianwen Dong Qiongzhi Gao Xin Cai Shengsen Zhang Teng Yuan Feng Peng Yueping Fang Siyuan Yang | 2023 | Journal of Energy Chemistry2023，，4： | 0 |
| 10 | Study of MRPC technology for BESIII endcap-TOF upgrade显示文摘Purpose In order to improve the charged particle identi-fication capability,end-cap time-of-flight(ETOF)detector of the Beijing Spectrometer(BESIII)has been upgraded with multi-gap resistive plate chamber(MRPC)technology,aiming at an overall time resolution of 80 ps for minimum-ionization particles to extend the K/πseparation(2σ)momentum range to 1.4 GeV/c.Methods The previous version of ETOF in BESIII consisted of plastic scintillators.The multi-hit events distort both shape and amplitude of the output signals.MRPC technique was chosen for the BESIII ETOF upgrade as it provides high time resolution and high detection efficiency,is of relatively low cost and is insensitive to neutral particles.Most importantly,the fine segmentation of the MRPC readout stripes can suppress multi-hit events effectively.Results The final design of MRPC module for ETOF is characterized by double-stack(2×6)structure,dual-end readout mode and precision electronics.To batch-produce and test these MRPC modules,a series of tools and production procedures as well as related performance simulation and test methods were developed.Results showed that each MRPC module’s intrinsic time resolution(including the electronics contribution)is around 50 ps and the efficiency is better than 97%.The overall performance of the upgraded ETOF is better than the designed index.The new ETOF has been successfully installed at BESIII and run in 2016. | Xin Li Yongjie Sun Cheng Li Zhen Liu Yuekun Heng Ming Shao Xiaozhuang Wang Zhi Wu Ping Cao Mingming Chen Hongliang Dai Shubing Liu Xiaolan Luo Xiaoshan Jiang Shengsen Sun Zebo Tang Weijia Sun Siyu Wang Meihang Xu Rongxing Yang Kejun Zhu | 2017 | Radiation Detection Technology and Methods2017，1，2： | 0 |
