DETAILED DESCRIPTION - Preparing single-layer metal structure/graphene composite involves synthsizing molybdenum disulfide precusor aqueous solution, and adding molybdenum disulfide precusor aqueous solution in single layer oxidized graphene aqueous solution to obtain molybdenum disulfide/oxidized graphene precusor aqueous solution. The ratio of oxidized graphene and molybdenum disulfide is 0.025-0.050. The molybdenum disulfide/oxidized graphene precusor aqueous solution is subjected to hydro-thermal treatment at 160 degrees C for 24 hours. The glass substrate and graphite electrode are inserted in molybdenum disulfide/oxidized graphene precusor aqueous solution to obtain single-layer metal structure of molybdenum/graphene composite film. The single-layer metal structure of molybdenum/graphene composite film is precipitated, filtered, washed, and dried at 80 degrees C to obtain molybdenum disulfide/graphene composite powder.
