| 1 | Reaction environment self-modification on low-coordination Ni^(2+)octahedra atomic interface for superior electrocatalytic overall water splitting显示文摘Large scale synthesis of high-efficiency bifunctional electrocatalyst based on cost-effective and earth-abundant transition metal for overall water splitting in the alkaline environment is indispensable for renewable energy conversion.In this regard,meticulous design of active sites and probing their catalytic mechanism on both cathode and anode with different reaction environment at molecular-scale are vitally necessary.Herein,a coordination environment inheriting strategy is presented for designing low-coordination Ni^(2+)octahedra(L-Ni-8)atomic interface at a high concentration(4.6 at.%).Advanced spectroscopic techniques and theoretical calculations reveal that the self-matching electron delocalization and localization state at L-Ni-8 atomic interface enable an ideal reaction environment at both cathode and anode.To improve the efficiency of using the self-modification reaction environment at L-Ni-8,all of the structural features,including high atom economy,mass transfer,and electron transfer,are integrated together from atomic-scale to macro-scale.At high current density of 500 mA/cm2,the samples synthesized at gram-scale can deliver low hydrogen evolution reaction(HER)and oxygen evolution reaction(OER)overpotentials of 262 and 348 mV,respectively. | Kaian Sun Lei Zhao Lingyou Zeng Shoujie Liu Houyu Zhu Yanpeng Li Zheng Chen Zewen Zhuang Zhaoling Li Zhi Liu Dongwei Cao Jinchong Zhao Yunqi Liu Yuan Pan Chen Chen | 2020 | Nano Research2020，13，11： | 12 |
| 2 | Ultra-deep desulfurization by reactive adsorption desulfurization on copper-based catalysts显示文摘In this paper,a novel copper-based catalyst for FCC gasoline improving the ability of removal the sulfur and avoiding the loss of the octane number from olefin saturation by reactive adsorption desulfurization(RADS) was investigated.The series of Cu/Zn O-Al_2 O_3 catalysts were characterized by X-ray powder diffraction(XRD),N_2 adsorption analysis and temperature-programmed reduction(TPR) studies,X-ray photoelectron spectroscopy(XPS),scanning electron microscope(SEM) and transmission electron microscopy(TEM).The experiment results showed that the catalysts had an optimum desulfurization ability with copper loading 6 wt%,which the sulfur contents of product decreased less than 10 μg/g and olefin contents decreased from 16.19% to 14.14% for the long period operation.The appropriate Cu loading content could lead to the high active and low apparent activation energy(E_a).Therefore,the Cu-based catalyst may become a novel catalyst for second-generation for reactive adsorption desulfurization,which achieves the high desulfurization active and low olefins saturation to satisfy the upgrading the product. | Yaqing Liu Hongying Wang Jinchong Zhao Yunqi Liu Chenguang Liu | 2019 | Journal of Energy Chemistry2019，28，2： | 6 |
| 3 | Fabrication of hierarchical porous ZnO and its performance in Ni/ZnO reactive-adsorption desulfurization显示文摘To investigate the effect of texture structure on the desulfurization performance in the Ni/ZnO reactive adsorption desulfurization(RADS) system,two kinds of ZnO porous materials with rod-shaped morphology were synthesized and their structure was characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM),transmission electron microscopy(TEM),and N2 adsorption/desorption.The formation mechanisms of hierarchical porous ZnO(ZnO with meso and macro pores) were also studied.Their application performance was evaluated in the RADS process over Ni/ZnO absorbent.Due to the difference in structure between the two kinds of ZnO,the two ZnO based adsorbents showed different desulfurization activity. | Liu Yunqi She Nannan Zhao Jinchong Peng Tingting Liu Chenguang | 2013 | Petroleum Science2013，10，4： | 6 |

| 10 | Synthesis and red electroluminescence of a dimesityl-functionalized bistetracene显示文摘A novel dimesityl-decorated bistetracene derivative 8,16-dimesityltetraceno[2,1,12,11-opqra]tetracene(DMTA) has been synthesized and characterized. Its single crystal analysis demonstrates that the parent bistetracene backbone is almost in a plane without any intermolecular 7 r-stacking interaction. DMTA exhibited the low-energy absorption at 560/607 nm and emission spectra at 617/663 nm, respectively.The fabricated device based on DMTA doping into 2,6-bis(3-(9 H-carbazol-9-yl)phenyl)pyridine(1 %) as an emitter present a maximum brightness of 632 cd/m^2 at 14.7 V with the CIE coordinate of(0.623,0.349). | Guixia Zhai Changting Wei Shulian Chen Xiaomeng Yin Jinchong Xiao Wenming Su | 2018 | Chinese Chemical Letters2018，29，2： | 0 |
| 11 | Low-Energy Driven Ring-Opening Behavior of Benzocyclobutene Derivatives显示文摘It's urgent to develop benzocyclobutene(BCB)-based polymers with low curing temperature for temperature-sensitive applications such as liquid crystal displays(LCDs)and flexible electronics.Herein,the effect of substituents on the ring-opening behavior of BCB derivatives was investigated.The ring-opening activation energy barriers(ΔGA)of BCB derivatives with one or two substituents on the four-membered alkyl ring were systematically calculated using the B3LYP function.Both mono-and di-substituted BCBs adopted the conrotatory ring-opening process,obeying the Woodward-Hoffmann's Rules upon heating.The mono-/di-substituted BCBs exhibited 8.2%—69%lowerΔGA compared with BCB,attributed to the electronic effects of the substituents.Disubstituted BCBs with both electron-donating and electron-withdrawing groups,e.g.,1-NH_(2)-8-NO_(2)-BCB,demonstrated the lowestΔGA.In addition,BCB derivatives with amide/ester/acyloxy group modified on C1 position were synthesized as model molecules,and their ring-opening temperature can be decreased by 20℃ compared to the unsubstituted one,also consistent with our calculation results.This work combined theoretical calculation methods with experimental results to provide valuable insights into the design and synthesis of BCB derivatives and next-generation BCB functional packaging materials with low ring-opening temperature. | Ziwei Yuan Quan Sun Jinchong Xiao Pingxia Zhang Konstantin S.Levchenko Dmitry Y.Demin Wenxin Fu | 2023 | Chinese Journal of Chemistry2023，41，23： | 0 |
| 12 | Our research progress in heteroaggregation and homoaggregation of organicπ-conjugated systems显示文摘Construction of crystalline homo/heteroaggregation at micro/nanometer level from organicπ-conjugated systems is of great importance because the controllable morphologies(i.e.,size,shape,and dimension)could provide diverse optoelectronic properties for different applications in the electrooptical devices.In this review,we summarize our recent progress in the self-assembly of micro/nanostructures of organicπ-conjugated molecules via the heteroaggregation and homoaggregation strategies.We also discuss various factors(i.e.,temperature,solvents,and surfactants)that affect the aggregation process through a surfactant-assisted reprecipitation method.Moreover,their physical properties and possible applications in electronics and biofields are illustrated. | Xin Deng Xiaohui Yu Jinchong Xiao Qichun Zhang | 2021 | Aggregate2021，2，3： | 0 |
