▎ 摘　　要

NOVELTY - Graphene, zinc sulfide or molybdenum disulfide nano-solid solution photocatalyst synthesis involves preparing graphene oxide by dispersing graphene oxide into an organic solvent ultrasonically to obtain uniform solution, and then dissolving inorganic zinc salt, inorganic molybdenum salt and sulfur source as raw materials into an organic solution. The resulting solution is added into the prepared graphene solution, and then transferred to a reaction vessel at 180-220 degrees C for 24 hours. The reactants are separately washed with deionized water and absolute ethanol, centrifuged multiple times, and vacuum dried at 60-100 degrees C for 6-24 hours to obtain visible light catalytic activity photocatalyst. USE - Method for synthesizing graphene, zinc sulfide or molybdenum disulfide nano-solid solution photocatalyst with visible light catalytic activity. ADVANTAGE - The method synthesizes the graphene, zinc sulfide or molybdenum disulfide nano-solid solution photocatalyst with large specific surface area, narrow and continuously adjustable band gap, effectively promoted photogenerated electron-hole separation and migration under visible light, strong light absorption and photocatalytic activity. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic X-ray powder diffraction pattern of the prepared nanosolid solution photocatalyst. (Drawing includes non-English language text).
