NOVELTY - Preparation of amorphous nano-porous titanium dioxide-supported graphene photocatalytic thin film involves forming a nano-porous thin film structure with uniform pore distribution and then oxidizing graphite through strong oxidizing agent and obtaining a graphene oxide solution, and then forming graphene oxide coating layer on surface of the amorphous nano-porous titanium dioxide strip by Czochralski method, and then carrying out oxidation/reduction reaction. USE - Preparation of amorphous nano-porous titanium dioxide-supported graphene photocatalytic thin film (claimed). ADVANTAGE - The method efficiently and economically provides amorphous nano-porous titanium dioxide-supported graphene photocatalytic thin film under low reaction conditions. DETAILED DESCRIPTION - Preparation of amorphous nano-porous titanium dioxide-supported graphene photocatalytic thin film involves applying constant-voltage to amorphous alloy strip in an electrochemical three-electrode system with 25-55% nitric acid solution as an electrolyte solution, using electrochemical workstation and carrying out constant-voltage electrochemical corrosion at45-85 degrees C for 3600-10800 seconds and voltage of 0.5-1.5V, and forming a nano-porous thin film structure with uniform pore distribution and then oxidizing graphite through strong oxidizing agent and obtaining a graphene oxide solution, and then forming graphene oxide coating layer on surface of the amorphous nano-porous titanium dioxide strip by Czochralski method, and then carrying out oxidation/reduction reaction.
