Copper-based nanocatalysts toward chemoselective hydrogenation reaction

Cu-based catalysts are widely used in various heterogeneous catalytic reaction systems,the precise control of their electronic structure is an intrinsic require-ment for the rational design of metal catalysts,and it is also an important basis for clarifying their structure-activity relationships.Changing the electronic structure of Cu-based catalysts is an important way to improve the catalytic hydrogenation performance of Cu-based catalysts by controlling the adsorption intensity be-tween the reaction adsorbate and the active center.In this paper,the application of selective hydrogenation of Cu-based catalysts is reviewed,with a special emphasis on the selective catalytic hydrogenation reduction of p-nitrostyrene and CO_(2).This review particularly emphasizes the application of Cu-based catalysts in the field of selective hydrogenation and discusses the influence of their different properties on selective hydrogenation performance.
