NOVELTY - Preparing molybdenum disulfide/graphene layered assembly, comprises e.g. (i) transferring graphene film containing silicon dioxide/silicon substrate into second heating furnace, placing molybdenum trioxide powder into above container, placing sulfur powder container into first heating furnace, then placing molybdenum trioxide container into second heating furnace, and introducing argon gas, (ii) under argon gas atmosphere, pressurizing tubular furnace, heating sulfur powder, heating molybdenum trioxide, then depositing molybdenum disulfide on the substrate, and cooling to obtain final product. USE - The method is useful for preparing molybdenum disulfide/graphene layered assembly (claimed). ADVANTAGE - The molybdenum disulfide/graphene layered assembly: has large surface area, high quality, the light intensity of 94 mu W/cm2, the photocurrent density reaches to 3 mu A/cm2, and the photocurrent response to light open-close instantly finished in 2.3 second. DETAILED DESCRIPTION - Preparing molybdenum disulfide/graphene layered assembly, comprises (i) transferring graphene film containing silicon dioxide/silicon substrate into second heating furnace of a tubular furnace using single quartz tube, placing molybdenum trioxide powder into above container, placing sulfur powder container into center of first heating furnace of the tubular furnace, then placing molybdenum trioxide container in center of the second heating furnace of the tubular furnace, and introducing argon gas, (ii) under argon gas atmosphere, pressurizing the tubular furnace to 133.29Pa, heating first heating zone to a volatilization temperature of the sulfur powder, heating second heating zone to a volatilization temperature of molybdenum trioxide, then depositing molybdenum disulfide on the substrate, and cooling to room temperature to obtain final product.
