▎ 摘　　要

NOVELTY - Graphene oxide film is prepared by performing electrophoretic deposition using glass sheet as anode, stainless steel sheet as cathode, and graphene oxide suspension as depositing medium. The obtained graphene oxide film is subjected to electrochemical process using graphene oxide film as working electrode, silver-silver chloride and platinum filament as reference electrode and auxiliary electrode, and reduced to obtain graphene film. Platinum nanoparticles are deposited on surface of graphene by performing electrochemical process to obtain graphene-containing compound film. USE - Preparation of graphene-containing compound film material used as electrode to analyze catalytic activity of methanol. ADVANTAGE - The method provides graphene-containing compound film material having excellent catalytic effect. DETAILED DESCRIPTION - A graphene oxide film is prepared by performing electrophoretic deposition using clean conductive glass sheet as anode, stainless steel sheet as cathode, and graphene oxide suspension as depositing medium to deposit at 150-160 V for 30-90 seconds. The obtained graphene oxide film is subjected to electrochemical process using graphene oxide film as working electrode, silver-silver chloride and platinum filament as reference electrode and auxiliary electrode, potassium chloride aqueous solution as electrolyte solution, and reduced graphene oxide through cyclic voltammetry or potentiostatic electrophoretic deposition to obtain graphene film. Platinum nanoparticles are deposited on the surface of graphene by performing electrochemical process at -0.25 V using reduced graphene film as working electrode, silver-silver chloride and platinum filament as reference electrode and auxiliary electrode, mixed solution of chloroplatinic acid and sulfuric acid as electrolyte solution, to obtain graphene-containing compound film.
