| 1 | 电催化还原CO_(2)生成多种产物催化剂研究进展显示文摘电催化还原CO_(2)生成含碳产物技术,能有效解决CO_(2)过量导致的温室效应及能源短缺问题。但是,电催化还原CO_(2)会生成多种产物,因此,研究制备催化活性较好的高选择性催化剂是研究重点。本文简述了电催化还原CO_(2)的基本原理、不同还原产物的形成途径、活性中间体、速控步及活性催化剂,分析了电催化还原CO_(2)生成不同产物存在的问题。并且针对催化剂催化活性及催化反应过程中的这些问题,提出了提高催化剂催化活性的方法,总结了催化剂发展趋势,一般策略包括制造纳米结构材料、催化剂负载在高比表面积的载体上、杂原子掺杂、合金化、引入缺陷等,分析了这些方法通过改变电子传输等因素对催化剂活性及选择性的影响。 | 郑元波 张前 石坚 李佳霖 梅苏宁 余秦伟 杨建明 吕剑 | 2022 | 化工进展2022，41，3： | 6 |
| 2 | On the occasion of the 80th birthday of Professor Yitai Qian:Celebrating 60 years of innovation in solid-state chemistry and nanoscience显示文摘Professor Yitai Qian,a pioneer in nanomaterials,an academician of the Chinese Academy of Sciences(CAS)and a professor at the University of Science and Technology of China(USTC),has committed his entire career to the development of solid-state chemistry and nanoscience in China.Prof.Qian is recognized for his pioneering contributions to the development of emerging high-Tc superconducting materials,and the development of solvothermal methodology for the synthesis of a wide range of low-dimensional nanomaterials.Beyond the landmarking scientific advancements he has made in his own trailblazing research,Prof.Qian has directly mentored more than 100 excellent PhD students,in addition to many more master and undergraduate students,many of them have gone on to become the leading scientists in China and worldwide in the field of nanoscience and beyond.Without exaggeration,the academic offspring and extended family of Prof.Qian have contributed a substantial portion of nanoscience and nanotechnology development over the past several decades. | Shu-Hong Yu Xiangfeng Duan Yi Xie Peidong Yang Yadong Li | 2021 | Nano Research2021，14，10： | 0 |
| 3 | Selectivity regulation of CO_(2)electroreduction on asymmetric AuAgCu tandem heterostructures显示文摘Rational design and synthesis of multimetallic nanostructures(NSs)are fundamentally important for electrochemical CO_(2)reduction reaction(CO_(2)RR).Herein,a multi-step seed-mediated growth method is applied to synthesize asymmetric AuAgCu heterostructures using Au nanobipyramids as nucleation seeds,in which their composition and structures are well controlled.We find that the selectivity of C_(2)products for CO_(2)RR could be effectively regulated by tandem catalysis and electronic effect over trimetallic AuAgCu heterostructures.Particularly,the Faraday efficiency toward ethanol could reach up to 37.5%at a potential of−0.8 V versus reversible hydrogen electrode over asymmetric Au1Ag1Cu5 heterostructures with segregated domains of three constituent metals.This work provides an efficient strategy for the synthesis of multicomponent architectures to boost their promising application in CO_(2)RR. | Yating Zhu Zengqiang Gao Zhicheng Zhang Ting Lin Qinghua Zhang Huiling Liu Lin Gu Wenping Hu | 2022 | Nano Research2022，15，9： | 0 |
