摘要
利用电催化方法还原CO2制备基础化学品,是当前清洁能源发展的方向之一。然而,在转化CO2为有价值的产品过程中,电催化材料面临的最大挑战是抑制析氢副反应的同时实现高效率、高选择性。铜基催化剂因其在电催化还原CO2过程中优异的催化性能而得到广泛关注。本文探究了CO2还原反应的基本原理,综述了以Cu基催化剂电化学还原CO2为醇类的研究现状及发展趋势。重点研究了形貌控制,改性材料等对Cu基催化剂性能的影响。并针对机理研究的现状,深入认识以醇类为目标产物的CO2电催化还原反应的关键,以期指导Cu基催化剂在工业应用方面的开发研究。
The conversion of CO2 into useful chemicals by using electrochemical reduction is one of the most promising strategies for the development of clean energy.However,it remains a large challenge to convert CO2 to valuable products with high efficiency and selectivity while suppressing the side reaction of H2 evolution.Copper-based catalyst attracts considerable attention currently due to its excellent catalytic performance for the electrochemical reduction of CO2.This article explores the basic principles of CO2 reduction reaction,and summarizes the research status and development trend of electrochemical reduction of CO2 with Cu-based catalysts as alcohols.The focus is on the influence of morphology control and modified materials on the performance of Cu-based catalysts.In view of the current situation of mechanism research,we will deeply understand the key to the CO2 electrocatalytic reduction reaction with alcohols as the target product,in order to guide the development and research of Cu-based catalysts in industrial applications.
