| 2 | Single-molecule imaging of dinitrogen molecule adsorption on individual iron phthalocyanine显示文摘Nitrogen fixation is a vital process for both nature and industry.Whereas the nitrogenase can reduce nitrogen in ambient environment in nature,the industrialized Haber-Bosch process is a high temperature and high-pressure process.Since the discovery of the first dinitrogen complex in 1965,many dinitrogen complexes are prepared in a homogeneous solution to mimic the nitrogenase enzyme in nature.However,studies of the heterogeneous process on surface are rarely addressed.Moreover,molecular scale characterization for such dinitrogen complex is lacking.Here,we present a simple model system to investigate,at the single-molecule level,the binding of dinitrogen on a surface confined iron phthalocyanine(FePc)monolayer through the combination of in-situ low-temperature scanning tunneling microscopy(LT-STM)and X-ray photoelectron spectroscopy(XPS)measurements.The iron center in FePc molecule deposited on Au(111)and highly oriented pyrolytic graphite(HOPG)surface can adsorb dinitrogen molecule at room temperature and low pressure.A comparative study reveals that the adsorption behaviors of FePc on these two different substrates are identical.Chemical bond is formed between the dinitrogen and the Fe atom in the FePc molecule,which greatly modifies the electronic structure of FePc.The bonding is reversible and can be manipulated by applying bias using a STM tip or by thermal annealing. | Chengding Gu Jia Lin Zhang Jian Qiang Zhong Qian Shen Xiong Zhou Kaidi Yuan Shuo Sun Xu Lian Zhirui Ma Wei Chen | 2020 | Nano Research2020，13，9： | 1 |
| 3 | Selenium Enriched Trionyx sinensis : A New Choice for the Sustainable Development Model of Modern Agriculture显示文摘Based on the analysis of the current situation and existing problems of traditional Chinese soft shelled turtle(Trionyx sinensis)breeding industry,combined with the fact that selenium enriched functional agriculture is the future demand of mankind,this paper put forward the necessity of developing selenium enriched Chinese soft shelled turtles and promoting the sustainable development of modern agriculture:the development of selenium-enriched Chinese soft-shelled turtle is the need of the consumer market for food safety,the need to reduce the production cost of soft-shelled turtles and improve the production efficiency of soft-shelled turtles,the need to enrich the Chinese soft-shelled turtle market,and the need to promote the sustainable development of modern agriculture(fishery). | Bo YANG Wei HUANG Xianghui QIN Jun YAN Chengde LIN Xiaofeng GAO Yinglan HUANG | 2021 | Agricultural Biotechnology2021，10，6： | 0 |
| 4 | Pressure-dependent band-bending in ZnO:A near-ambient-pressure X-ray photoelectron spectroscopy study显示文摘ZnO-based catalysts have been intensively studied because of their extraordinary performance in lower olefin synthesis,methanol synthesis and water-gas shift reactions.However,how ZnO catalyzes these reactions are still not well understood.Herein,we investigate the activations of CO_(2),O_(2)and CO on single crystalline ZnO polar surfaces at room temperature,through in-situ near-ambient-pressure X-ray photoelectron spectroscopy(NAP-XPS).It is revealed that O_(2)and CO_(2)can undergo chemisorption on ZnO polar surfaces at elevated pressures.On the ZnO(0001)surface,molecular CO_(2)(O_(2))can chemically interact with the top layer Zn atoms,leading to the formation of CO_(2)^(δ-)(O_(2)^(δ-))or partially dissociative atomic oxygen(O-)and hence the electron depletion layer in ZnO.Therefore,an apparent upward band-bending in ZnO(0001)is observed under the CO_(2)and O_(2)exposure.On the ZnO(0001)surface,the molecular chemisorbed CO_(2)(O_(2))mainly bond to the surface oxygen vacancies,which also results in an upward bandbending in ZnO(0001).In contrast,no band-bending is observed for both ZnO polar surfaces upon CO exposure.The electron-acceptor nature of the surface bounded molecules/atoms is responsible for the reversible binding energy shift of Zn 2 p_(3/2)and O 1 s in ZnO.Our findings can shed light on the fundamental understandings of CO_(2)and O_(2)activation on ZnO surfaces,especially the role of ZnO in heterogeneous catalytic reactions. | Zhirui Ma Xu Lian Kaidi Yuan Shuo Sun Chengding Gu Jia Lin Zhang Jing Lyu Jian-Qiang Zhong Lei Liu Hexing Li Wei Chen | 2021 | Journal of Energy Chemistry2021，30，9： | 0 |
