NOVELTY - Preparing copper sulfide-graphene composite aerogel involves pouring the solvent into the container, adding the copper source and the sulfur source in proportion, and stirring until the copper source and the sulfur source are completely dissolved to form a copper-sulfur solution, measuring certain amount of graphene oxide aqueous solution, adding to the copper-sulfur solution, stirring for 1-5 hours to obtain a copper-sulfur-graphene oxide mixed solution, measuring certain amount of catalyst, adding to the copper-sulfur-graphene oxide mixed solution, stirring for 10-60 minutes, transferring the mixed solution to the oven and leaving to stand to obtain copper sulfide-graphene wet gel, adding ethanol to the copper sulfide-graphene wet gel for aging, and then dried to obtain product. USE - Method for preparing copper sulfide-graphene composite aerogel. ADVANTAGE - The method has short reaction period, and prospect of mass production, in simple manner.
