▎ 摘　　要

NOVELTY - Nano-complex photocatalyst with visible light activity comprises catalyst as an oxidized graphene/titanate nanotube complex photocatalyst. USE - Used as nano-complex photocatalyst with visible light activity. ADVANTAGE - The complex photocatalyst has a large specific surface area, strong ability of absorbing pollutants, visible light activity and long service life; rapidly decomposes pollutants; and can be repeatedly used. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing nano-complex photocatalyst comprising adding graphene oxide and titanium dioxide nanoparticles in a reaction kettle and solvent thermal reacting at 120-180 degrees C for 12-24 hours.
