NOVELTY - Preparing a platinum-graphene-molybdenum sulfide composite material by low-temperature plasma involves mixing potassium chloroplatinate with a concentration of 24.09 mmole/L, molybdenum sulfide and graphene oxide solution of the same concentration in a volume ratio of 1:5:5 to obtain a mixed solution. The mixed solution is sonicated for 20-40 minute to obtain a dispersion. The dispersion is centrifuged and the separated compound is freeze-drying. The obtained powder is subjected to low-temperature plasma discharge in a hydrogen atmosphere to obtain a platinum-graphene-molybdenum sulfide composite. USE - Method for preparing platinum-graphene-molybdenum sulfide composite material. ADVANTAGE - The method is simpler, has lower requirements, and is suitable for large-scale production to improve efficiency and reduce costs.
