▎ 摘　　要

NOVELTY - A non-noble metal phosphide catalyst is prepared by chemically plating nickel-phosphorus plating layer on conductive material, preparing non-noble metal layered hydroxide on chemically plated nickel-phosphorus plating layer, and calcining material under reducing atmosphere. USE - The method is used for preparing non-noble metal phosphide catalyst. ADVANTAGE - The catalyst can replace noble metal catalyst, and has good catalytic performance to hydrogen evolution reaction of electrolytic water process.
