Cu基催化剂电催化还原CO2的性能调控及其产物的研究进展
Research Progress on Properties Tuning and Products of Cu-Based Catalyst in Electrocatalytic CO2 Reduction
摘要
Abstract
Ecological deterioration and energy reform have been caused by long-term carbon emissions.How to solve this problem is a hot research topic at present.Electricity generated from renewable energy sources can be electrocatalytic CO2 reduction(eCO2R)into hydrocarbon fuel or value-added chemical raw materials,meanwhile,alleviating environmental and energy problems,thus showing broad application prospects.The low-cost transition metal Cu featuring a unique electronic structure has a poor affinity for hydrogen and oxygen,which can reduce CO2 to a wide range of economically valuable carbon products,making it a prime material for eCO2R.However,the size,crystal face,structure,and composition of the catalysts significantly affect the activity and selectivity of eCO2R.At present,after continuous research on modification,various Cu-based catalysts derived from metal Cu make the products as well as the reaction paths differ greatly from one catalyst to another due to the differences in activity and selectivity.This review systematically de-scribed the design of the Cu-based catalyst for eCO2R based on these factors.In addition,various catalytic products of Cu-based cata-lyst eCO2R were systematically summarized.The possible paths and mechanisms of eCO2R forming different carbon products were elu-cidated.Finally,based on the current research focus and shortcomings,the outlook of eCO2R was proposed and provided a reference for the realization of the carbon peak and neutrality goals.关键词
