NOVELTY - Preparing transition metal heterogeneous structure electro-catalysis hydrogen production catalyst comprises (i) preparing graphene oxide by hummer method, (ii) mixing urea, ethylenediamine and transition metal salt, drying and melting, and (iii) decomposing the mixture after melting and cooling at high temperature to prepare heterogeneous structure. USE - The method is useful for preparing transition metal heterogeneous structure electro-catalysis hydrogen production catalyst. ADVANTAGE - The method can be controlled by simple melting and high temperature decomposition method to control the heterogenous structure material, and the material has excellent electro catalytic hydrogen production performance under the alkaline condition. The method is simple, easy to operate, and can be industrial production in a large scale. The prepared catalyst has high activity, excellent stability, excellent electro-catalytic performance, and high economic benefit.
