Abstract

The present invention provides a CuH catalyst, a CuH-derived catalyst, a preparation method and an application. The CuH catalyst is prepared by a liquid-phase chemical method using a borane complex or the like as a reducing agent. Preparation of CuH catalyst with uniform particle size distribution and relatively pure crystal, the preparation method is simple, and suitable for large-scale production; the prepared CuH catalyst has a rough active surface, and can spontaneously derivatize into a series of different Cu-based crystal phases in air or oxygen The catalyst has a simple process and does not require complicated surface plasma treatment and heat treatment to control the crystal phase structure of Cu-based catalysts; Cu-based catalysts derived from CuH catalysts 2 O / CuO mixed crystalline phase catalysts exhibit excellent electrochemical CO 2 Restoration performance, C 2 H 4 Selectivity, multi-carbon product selectivity, and industrial-level current density electrolysis and catalytic stability can be realized; the present invention can realize Cu-based catalyst electrocatalytic CO 2 Reduction to prepare C 2 H 4 wait C 2+ Industrial application of chemicals.
