Abstract
The present invention relates to the technical field of nano-materials, and specifically provides a method for preparing multiphase heterojunction nanomaterials. The method comprises the following steps: providing a substrate loaded with a NiMoOprecursor; dissolving a selenium powder in hydrazine hydrate, adding water or sodium molybdate aqueous solution, then adding the substrate loaded with a NiMoOprecursor, and reacting at 180-200° C.; and after the reaction, obtaining the multiphase heterojunction nanomaterials. The present invention also provides a tetraphase heterojunction nanomaterial 1T/2H-MoSe—H/R—NiSe, and a triphase heterojunction nanomaterial 1T/2H-MoSe—H—NiSe prepared by the method, and use thereof as an electrocatalyst to catalyze a hydrogen evolution reaction under an alkaline condition. The multiphase heterojunction nanomaterials prepared in the present invention possess large double-layer capacitance, large electrochemical active specific area and low charge transfer resistance, thus greatly improving the activity and stability of electrocatalytic hydrogen production.
