How to select heterogeneous CO_(2)reduction electrocatalyst

As an important part of carbon neutralization,carbon dioxide electroreduction reaction(CO_(2)RR)can convert CO_(2)into high value-added chemicals and fuels to realize the recycling of carbon resources and solve the problem of environmental pollution.Therefore,exploring the element species and surface structure of the catalyst plays a central role in improving the performance of the catalyst,enhancing the CO_(2)conversion efficiency and forming C1 and C_(2+)products.Here,we summarize the recent progress in the selective regulation of CO_(2)RR reaction products by different elements.In particular,we emphasize the structure-property relationship of CO_(2)RR by the microenvironment of metal center and substrate,heteroatom doping,hydrogen bond network of metal-free polymer,and construction of heterogeneous catalytic system.At the same time,the recent advances for the identification of CO_(2)RR active sites and mechanistic studies on the process of reducing CO_(2)conversion to different products are reviewed,as well as a comprehensive review to the final products.Finally,we outline the inevitable challenges faced by CO_(2)RR and present our own recommendations aimed at contributing to CO_(2)resource utilization.
