NOVELTY - The preparation method of silver-doped nanorod composite film involves weighing indium tin oxide as substrate, graphene thin film, titanium tetrachloride and tetrabutyl titanate as precursors and silver acetylacetonate as silver-doped ion and hydrothermally processing. USE - The method is useful for preparation of silver-doped nanorod composite film, which is useful for photocatalytic degradation of volatile organic compounds. ADVANTAGE - The method enables simple preparation of silver-doped nanorod composite film with excellent photocatalytic performance in environmentally-friendly manner.
