▎ 摘  要

NOVELTY - The method involves obtaining a base material on which an iron-doped carbon precursor is supported on a porous conductive carrier. The metal nano-clusters are supported on the base material, and the high-temperature pyrolysis is performed to the iron single-atom-doped carbon material-supported metal nano-cluster composite catalyst. The metal nanoclusters include one or a combination of two or more of gold nanoclusters, platinum nanoclusters, palladium nanoclusters, silver nanoclusters and copper nanoclusters. The porous conductive carrier is selected from one or a combination of two or more of foamed nickel, foamed copper and graphene foam materials. USE - Method for preparing metal nano-cluster composite catalyst supported by iron single-atom doped carbon material for use in electrolysis of water and for catalyzing cathodic hydrogen evolution reaction and anodic oxygen evolution reaction of electrolyzed water (all claimed). ADVANTAGE - The composite catalyst with iron-single-atom-doped carbon material loaded with metal nanoclusters has high catalytic activity, good stability, and simple synthesis method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a metal nano-cluster composite catalyst supported by iron single-atom doped carbon material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the scanning electron microscope image of the composite catalyst loaded with copper nanoclusters.
