【摘要】 随着工业化进程的快速推进，CO₂排放量预计将持续上升，CO₂捕获、储存和再利用受到研究者们的广泛关注。在各类CO₂转化技术中，电催化技术因其反应条件温和可控、能耗低、环境污染小等优点，是最有前途的策略之一。近些年来，CO₂选择性地转化为气态产物如一氧化碳、合成气、甲烷、乙烯和乙烷已有许多报道。本文对电催化CO₂还原生成气体产物的反应机理和催化剂设计策略进行了介绍；对电催化CO₂还原进行了总结与展望，包括新型电催化剂、机理研究、外部因素的影响以及级联反应。更多还原

【Abstract】 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 CO₂conversion 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.更多还原
