▎ 摘　　要

NOVELTY - Manufacture of reduced graphene oxide-titanium dioxide nanotube structure involves forming a reduced graphene oxide film on a titanium substrate, growing titanium dioxide nanotubes between the substrate and the reduced graphene oxide film, obtaining reduced graphene oxide-titanium dioxide nanotubes having anatase phase, and forming titanium dioxide nanoparticles having anatase phase on inner and outer surfaces of reduced graphene oxide film of the reduced graphene oxide-titanium dioxide nanotubes. USE - Manufacture of reduced graphene oxide-titanium dioxide nanotube structure used for photocatalyst (all claimed). ADVANTAGE - The method enables manufacture of reduced graphene oxide-titanium dioxide nanotube structure having improved light absorption rate at all wavelength ranges to promote charge transfer. The reduced graphene oxide-titanium dioxide nanotube structure effectively separates electron-electrical hole and prevents recombination of electron-electrical hole. The photocatalyst using the reduced graphene oxide-titanium dioxide nanotube structure has excellent photocurrent density and optical characteristics. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for reduced graphene oxide-titanium dioxide nanotube structure.
