Copper‐based nanocatalysts toward chemoselective hydrogenation reaction

Abstract Cu‐based catalysts are widely used in various heterogeneous catalytic reaction systems, the precise control of their electronic structure is an intrinsic requirement 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 between 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.
