摘　　要：二氧化碳催化氢化合成多碳化合物的研究对于减少碳排放和实现碳资源的可再生利用具有重要意义。本文总结概述了近年来二氧化碳氢化合成多碳化合物催化体系研究进展,着重介绍了低温下催化CO_(2)氢化合成多碳烃或多碳醇的金属纳米簇基催化剂的研究进展,讨论了CO_(2)氢化反应中C1和C_(2+)产物选择性调控的化学基础,介绍了具有低温催化CO_(2)氢化合成多碳化合物功能和高C_(2+)化合物选择性的PtRu双金属纳米簇催化剂的合成和构-效关系研究进展。在此基础上,进一步阐述了所提出的金属纳米簇催化剂局域电荷分布效应理论。Selectively catalytic hydrogenation of CO_(2)to multi-carbon compounds is of great significance for reducing carbon dioxide emissions and regenerating carbon-containing resources.In this review,we summarize the development of catalytic systems for CO_(2)hydrogenation to multi-carbon compounds in recent years.The development of metal nanocluster catalysts for CO_(2)hydrogenation to multi-carbon hydrocarbons or alcohols at low temperatures are introduced,and the chemical basis for regulating C1 and C_(2+)product selectivity in CO_(2)hydrogenation is discussed.The progresses in preparing and understanding the structure-function relationship of Pt-Ru bimetallic nanocluster catalysts with the high selectivity for C_(2+)compounds in the CO_(2)hydrogenation at low temperatures are discussed.Finally,we elaborate the theory of local charge distribution effect of metal nanocluster catalysts.
