▎ 摘　　要

NOVELTY - The material has a nitrogen-doped graphene substrate, where the surface of the nitrogen-doped graphene substrate is attached with rhodium-palladium double (RhPd) double-metal layered hydroxide. The surface of the RhPd double-metal layered hydroxide is deposited with compound of p-methyl aniline and benzidine. USE - Method for preparing super-hydrophilic composite material based on large current density hydrogen evolution reaction. ADVANTAGE - The method enables to prepare super-hydrophilic composite material that has excellent catalytic activity and chemical activity, low intensity and stability, hydrophilic, chemical activity and corrosion resistance, high temperature oxidation resistance, and high strength, hardness and strength, and improves the use effect of the material, and hydrogen evolution electrochemical performance of the composite material by using chemical vapor deposition method to deposit a compound of p-methyl aniline and benzidine on the surface of material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing super-hydrophilic composite material based on large current density hydrogen evolution reaction. DESCRIPTION OF DRAWING(S) - The drawing shows a performance test recording table (Drawing includes non-English language text).
