With the rapid advancement of industrialization,CO2 emissions are expected to continue to rise,and carbon dioxide capture,storage and reuse have been received widespread attention from researchers.In various CO2 conversion technologies,electrocatalytic technology is one of the most promising strategies because of its mild and controllable reaction conditions,low energy consumption and low environmental pollution.In recent years,there have been many reports on the selective conversion of CO2 into gaseous products such as carbon monoxide,syngas,methane,ethylene and ethane.In this paper,the reaction mechanism and catalyst design strategies of electrocatalytic CO2 reduction to gas products are introduced.The electrocatalytic CO2 reduction is summarized and prospected,including new electrocatalysts,mechanism studies,the influence of external factors and cascade reactions.
