| 1 | Recent progress of electrochemical reduction of CO_(2)by single atom catalysts显示文摘Powered by electricity from renewable energies,electrochemical reduction of CO_(2)could not only efficiently alleviate the excess emission of CO_(2),but also produce many kinds of valuable chemical feedstocks.Among various catalysts,single atom catalysts(SACs)have attracted much attention due to their high atom utilization efficiency and expressive catalytic performances.Additionally,SACs serve as an ideal platform for the investigation of complex reaction pathways and mechanisms thanks to their explicit active sites.In this review,the possible re-action pathways for the generation of various products(mainly C1 products for SACs)were firstly summarized.Then,recent progress of SACs for electrochemical reduction of CO_(2)was discussed in aspect of different central metal sites.As the most popular and efficient coordination modulation strategy,introducing heteroatom was then reviewed.Moreover,as an extension of SACs,the development of dual atom catalysts was also briefly discussed.At last,some issues and challenges regarding the SACs for CO_(2)reduction reaction(CO_(2)RR)were listed,followed by corresponding suggestions. | Tian Wang Jincheng Zhang Fuhua Li Bin Liu Sibudjing Kawi | 2022 | Materials Reports(Energy)2022，2，3： | 1 |
| 2 | Fe–N–C single atom catalysts for the electrochemical conversion of carbon,nitrogen and oxygen elements显示文摘Single atom catalysts(SACs)are constituted by isolated active metal centers,which are heterogenized on inert supports such as graphene,porous carbon,and amorphous carbon.The thermal stability,electronic properties,and catalytic activities of the metal center can be controlled via manipulating the neighboring heteroatoms such as nitrogen,oxygen,and sulfur.Due to the atomical dispersion of the active catalytic centers,the amount of metal required for catalysis can be decreased.Furthermore,new possibilities are offered to easily control the selectivity of a given transformation process as well as to improve turnover frequencies and turnover numbers of target reactions.Among them,Fe–N–C single atom catalysts own special electronic structure,and have been widely used in many fields of electrocatalysis.This review aims to summarize the synthesis of Fe–N–C based on anchoring individual iron atoms on carbon/graphene.The spin-related properties of Fe–N–C catalysts are described,including the relation between spin and electron structure of Fe–N x as well as the coupling between electronic structure of Fe–N x and electronic(orbit)of CO_(2),N_(2)and O_(2).Next,mechanistic investigations conducted to un-derstand the specific behavior of Fe–N–C catalysts are highlighted,including C,N,O electro-reduction.Finally,some issues related to the future developments of Fe–N–C are put forward and corresponding feasible solutions are offered. | Jian Huang Qiao Zhang Jie Ding Yueming Zhai | 2022 | Materials Reports(Energy)2022，2，3： | 1 |
| 3 | 钴基催化剂电催化还原CO_(2)研究进展显示文摘将CO_(2)在可再生电力驱动下电催化还原成燃料,用于替代化石燃料和应对CO_(2)排放增加导致的气候变化问题是一种潜在的清洁战略。主要综述了各种钴基催化剂在电催化CO_(2)还原方面的应用。金属钴催化性能较差,法拉第效率低于85%。然而,钴氧化物、钴酞菁、钴卟啉、钴基金属有机框架和共价有机框架通过金属参杂、碳基材料固定等手段能显著提高稳定性和催化性能。目前,CO_(2)的还原主要产生C_1和C_2产物,而较难生产C_3和C_4产物。此外,竞争性析氢反应抑制了CO_(2)还原。未来,高效性和专一性催化剂的研发是CO_(2)资源化回收的关键。 | 董仲珍 冯强 郑鑫 | 2022 | 河北环境工程学院学报2022，32，4： | 0 |
