摘　　要：二氧化碳的催化还原有望实现温室气体的转化和回收,同时也能生成一些如甲醇、乙醇等低相对分子质量的经济性产物。不仅如此,二氧化碳的催化还原也可以实现碳循环,以达成我国制定的2030年“碳达峰”,2060年实现“碳中和”的目标。电催化还原二氧化碳相比于光催化以及光电混合催化而言,具有能耗低、不限场地、反应条件简单的优势,但同时其对催化剂的性能要求较高。本文比较了Cu-Ag合金与Ag单质催化性能上的差异,对相关催化剂的研究做了铺垫。The catalytic reduction of carbon dioxide is expected to achieve the conversion and recovery of greenhouse gases,but also can generate some economic products such as methanol,ethanol and other low molecular weight.In addition,the catalytic reduction of carbon dioxide can also realize the carbon cycle,so as to achieve the goal of"carbon peak"by 2030 and"carbon neutrality"by 2060,which has been set by China in 2020.Compared with photocatalysis and photohybrid catalysis,electrocatalytic reduction of carbon dioxide has the advantages of low energy consumption,no limitation of sites and simple reaction conditions,but at the same time,it requires higher performance of the catalyst.In this paper,the difference of catalytic performance between Cu-Ag alloy and Ag elemental has been compared,which has paved the way for the research of related catalysts.
