▎ 摘  要

NOVELTY - Preparing nitrogen-substituted graphene/copper oxide photocatalytic film material grown in situ on flexible copper mesh, comprises dissolving sodium hydroxide in deionized water to obtain solution A, introducing sodium chloride to solution A and stirring to obtain solution B, introducing polyethylenene glycol to solution B to obtain solution C, using graphite as the cathode, copper mesh as the anode, and solution C as the electrolyte to oxidize the anode, repeatedly rinsing with deionized water to obtain product D with the copper mesh attached to the brick red substance, grinding and mixing urea and ammonium persulfate to obtain powder E, and placing product D on powder E, annealing treatment. USE - The method is useful for preparing nitrogen-substituted graphene/copper oxide photocatalytic film material grown in situ on flexible copper mesh. ADVANTAGE - The method has low requirement, small external influence, simple method, low cost, high controllability, and suitable for large-scale industrial production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for flexible copper net prepared by the method.
