NOVELTY - Method for preparing molybdenum disulfide/graphene composite material, involves (i) placing a molybdenum source material, inducer and graphene oxide in deionized water, stirring, adjusting the pH of the system to a pH of 0.8-2 with a dilute acid solution, and continuously stirring at room temperature to obtain a first mixed solution, (ii) adding thiourea to the first mixed solution, and continuously stirring until the solution turns light blue to obtain a second mixed solution, (iii) hydrothermally reacting the second mixed solution, and (iv) after the hydrothermal reaction is stopped, washing and drying the product obtained by the hydrothermal reaction to obtain the target material comprising a high proportion of 1T-MoS2. USE - The method is used for preparing the composite material for electrolysis of hydrogen and lithium ion battery electrode material. ADVANTAGE - The method adopts simple process, has moderate reaction conditions, is easy to scale production, provides the composite material which comprises an anchored 1T phase and 2H phase ultra-thin molybdenum disulfide sheet layer, and forms a stable ternary heterojunction with graphene, where the content of 1T-MoS2 reaches more than 80%, and the active site exposure of the material is high.
