摘　　要：随着日益增长的能源需求,人类社会对于传统碳基化石能源过度依赖,不仅加速了地球上有限能源储备的消耗,还导致大气中二氧化碳(CO_(2))不断累积。如何对二氧化碳进行可持续的捕获再利用,实现高效的零碳网络循环,已成为人类亟需解决的重大挑战之一。近年来,使用绿色可持续电力的电化学二氧化碳还原反应(CO_(2)RR)生产增值化学品成为研究热点。本文首先介绍了CO_(2)RR的基本电化学反应原理;然后总结了电化学还原CO_(2)制备甲酸/甲酸盐的主要金属基催化剂,着重介绍了Bi、Sn、In三类金属基催化剂的设计调控策略;进一步概括了电化学相关的原位表征手段,分别介绍了原位光谱技术和原位X射线表征技术;最后对电催化二氧化碳还原研究领域的未来发展进行了展望。With the ever-increasing energy demand,human society is over-reliant on traditional carbonbased fossil energy,which not only accelerates the consumption of the earth’s limited energy reserves,but also leads to the continuous accumulation of carbon dioxide(CO_(2))in the atmosphere.How to sustainably capture and reuse CO_(2)and achieve an efficient zero-carbon network cycle has become one of the major challenges that human beings urgently need to solve.In recent years,electrocatalytic CO_(2)reduction reaction(CO_(2)RR)production of value-added chemicals using green sustainable electricity has become a research hotspot.In this review,we firstly introduce the basic electrochemical reaction principle of CO_(2)RR.Then we summarize the main metal-based catalysts for the electrochemical reduction of CO_(2)to prepare formic acid/formate,and focus on the design and regulation strategies of three metal-based(Bi,Sn and In)catalysts.In addition,we generalize the in situ characterization methods related to CO_(2)RR,including in situ spectroscopic techniques and in situ X-ray characterization technique.Finally,the future opportunities and challenges for the electrocatalytic CO_(2)reduction are prospected.
