电催化CO2还原制甲酸p区金属基催化剂原位重构的研究进展
Research progress on in situ reconstruction of p-block metal-based catalysts for electrocatalytic CO2 reduction to formic acid
摘要
Abstract
Electrocatalytic CO2 reduction reaction(ECO2RR)for producing high value-added chemicals and fuels is an effective approach to achieving"dual carbon"goals,with formic acid(HCOOH)being one of the most economically valuable products.However,the thermodynamic stability of CO2 molecules and the multi-proton-electron coupling processes during ECO2RR limit the reaction activity and product selectivity.p-block metal-based(such as Bi,In,Sn,etc.)catalysts show significant potential in ECO2RR to HCOOH,owing to their appropriate key formic acid intermediate OCHO* adsorption capability.Under electrochemical operating conditions,the catalyst surface undergoes reconstruction induced by electric fields,interfacial reactions and changes of chemical environments.This reconstruction makes it difficult to reveal the relationship between the structure and catalytic performance of catalysts.In light of this,focusing on the in situ reconstruction behavior of p-block metal-based catalysts during ECO2RR,the influencing factors,reconstruction types and characterization techniques were systematically analyzed,and the structure-performance relationships of catalysts under dynamic operating conditions were explored,and different reconstruction pathways and evolution laws of active sites of p-block metal-based catalysts during ECO2RR to HCOOH were summarized.A suggestion was put forward to construct a"theoretical calculation-machine learning-in situ experiment"system,providing a reference for designing reconstructed catalysts with high stability and product selectivity.关键词
