NOVELTY - Three-dimensionally ordered orientation disulfide/graphene-efficient optical catalytic hydrogen production composite nanomaterial comprises layered molybdenum disulfide equably and vertically distributed on tooth graphene nanosheet surface forming three-dimensionally ordered orientation material. USE - Three-dimensionally ordered orientation disulfide/graphene-efficient optical catalytic hydrogen production composite nanomaterial. ADVANTAGE - The nanomaterial promotes transfer of photogenerated electrons, enhances photon absorption and optimizes charge transfer. The nanomaterial has large surface area while three-dimensional ordering exposes more active sites toward the array of molybdenum disulfide, simple preparation and low cost. The nanomaterial can be directly grown on ordinary transparent glass. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the nanomaterial comprising preparing three-dimensional graphene by ultrasonically cleaning, placing UV-cleaned glass in plasma-enhanced chemical vapor deposition apparatus, using mixture of water and ethanol having volume ratio of 1-2 as precursor solution at 0.8-1.0 ml/minute, controlling pressure at 50-100 Pa, injecting precursor solution into plasma enhanced chemical vapor deposition system, growing at 1100-1200 degrees C with 50-100 Pa environment for 2-6 hours, and naturally cooling to room temperature to obtain three-dimensional graphene; and depositing 15-25 nm thick molybdenum trioxide film on three-dimensional graphene sheet by thermal vaporizer evaporation, placing heating center area of tube furnace, placing sulfur powder upstream of tube furnace, setting pressure of tube furnace to 200-400 Pa, maintaining atmosphere in tube using argon gas with flow rate of 100-120 cm3/second, heating center to 550-650 degrees C for 20-30 minutes, maintaining sulfur powder at 220 degrees C, reacting for 10-15 minutes, and natural cooling.
