研发高效的CO2电还原催化剂对减少碳排放、实现碳中和具有重要意义。单一金属催化剂如单原子催化剂因其良好的催化性能在CO2电还原领域得到广泛研究。然而,单一金属催化剂存在活性位点单一、反应动力学慢、产物选择性低和稳定性不足等缺点。双金属催化剂因其独特的结构和优异的性能而受到极大关注。通过引入另一种金属,可以改变催化剂的电子结构,促进新的活性位点的形成,从而优化中间体与活性位点之间的相互作用。文章从衍生材料的制备策略、双金属材料的优势剂在电催化二氧化碳领域的应用等角度具体阐述了双金属衍生材料在电催化碳还原领域的研究进展。Developing efficient CO2 electroreduction catalysts is of great significance for reducing carbon emissions and achieving carbon neutrality. Single metal catalysts such as single atom catalysts have been widely studied in the field of CO2 electroreduction due to their excellent catalytic performance. However, single metal catalysts have disadvantages such as single active sites, slow reaction kinetics, low product selectivity, and insufficient stability. Bimetallic catalysts have attracted great attention due to their unique structure and excellent performance. By introducing another metal, the electronic structure of the catalyst can be altered, promoting the formation of new active sites and optimizing the interaction between intermediates and active sites. This article presents the research progress of bimetallic-derived materials in the field of electrocatalytic carbon reduction, focusing on the preparation strategies of derived materials and the application of dominant agents of bimetallic materials in the field of electrocatalytic carbon dioxide reduction.
