CO_(2)RR稀土基催化剂的研究进展

Research Progress on Rare Earth⁃Based Catalysts for CO_(2) Reduction Reaction(CO2RR)

化石燃料的大规模使用导致CO_(2)过度排放,造成气温升高、冰川融化、病虫害加剧等一系列问题。通过电化学还原CO_(2)(CO_(2)RR)将CO_(2)转化为有价值的化学品和燃料,已成为实现碳循环的一种途径。多年来,已将金属及其氧化物、碳基材料、单原子催化剂等不同电催化剂用于CO_(2)RR并取得了一定的进展,但作为“工业维生素”的稀土元素用于CO_(2)RR的报道较少。综述了稀土元素作为载体、主催化剂、助催化剂用于CO_(2)RR的情况,探究了稀土元素材料在CO_(2)RR中的催化性能,以期促进对工业应用的研究。

The large⁃scale use of fossil fuels has led to excessive CO_(2) emissions,resulting in a series of problems such as rising temperatures,melting glaciers,and the accumulation of diseases and pests.Using electrochemical reduction of CO_(2)(CO_(2)RR)to convert CO_(2) into valuable chemicals and fuels has become a way to realize the carbon cycle.Over the years,good progress has been made in using metals and their oxides,carbon based materials,monatomic catalysts and other electrocatalysts for CO_(2)RR,but rare earth metals as"industrial vitamins"have been rarely reported for CO_(2)RR.This paper summarizes the application of rare earth elements as carriers,main catalysts and cocatalysts in CO_(2)RR,and explores the catalytic performance of rare earth materials in CO_(2)RR,so as to promote practical research of industrial application.
