▎ 摘　　要

NOVELTY - Preparation of titanium dioxide-modified nitrogen-doped graphene oxide UV photocatalytic film involves obtaining a titanium dioxide dispersion by titanate hydrolysis, performing hydrothermal synthesis of graphene oxide and nitrogen source to obtain a nitrogen-doped graphene oxide, and adding the nitrogen-doped graphene oxide, a film raw material, and a pore-forming agent to the titanium dioxide dispersion. USE - Preparation of titanium dioxide-modified nitrogen-doped graphene oxide UV photocatalytic film. ADVANTAGE - The method is rigorous in operation, and produces titanium dioxide-modified nitrogen-doped graphene oxide UV photocatalytic film having stable structure and excellent UV catalytic performance, by one-step process.
