NOVELTY - Preparing phosphorus (P)-molybdenum disulfide (Mo2S)/graphene oxide (NGAs) composite material comprises (i) adding ethylenediamine to the suspension of graphene oxide, stirring, and carrying out hydrothermal reaction to obtain graphene oxide (NGAs), (ii) mixing sodium molybdate, thiourea and water, and performing ultrasonic dispersion to obtain a mixed solution, (iii) performing hydrothermal reaction to the mixed solution and NGAs to obtain Mo2S/NGAs, and (iv) calcining the Mo2S/NGAs and sodium hypophosphite into a composite material. USE - Preparation method of phosphorus-molybdenum disulfide/graphene oxide composite material used as electro-catalysis hydrogen evolution material (claimed) for rechargeable battery and sound absorbing material. ADVANTAGE - The raw material cost of the P-Mo2S/NGAs hydrogen evolution material prepared by the method is low; the preparation method is simple; the hydrogen evolution effect in the alkaline solution is good; it is expected to face industrial development; and the synthesis cost is lower than the majority of catalyst, the earth reserve of the main element is sufficient. The hydrogen evolution performance of the aerogel is greatly enhanced after combining with the graphene gas gel. The electrochemical performance is improved. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) Mo2S/NGAs composite material; and (2) application of the P-Mo2S/NGAs composite material as the electro-catalysis hydrogen evolution material.
