▎ 摘  要

NOVELTY - A graphene-niobium-doped titania nanotube heterogeneous structure photocatalyst is prepared by using isopropyl alcohol as solvent and tetrabutyl titanate as precursor, solvent thermal method to prepare surface-modified supported nanotitanium dioxide catalyst, and coupling with graphene oxide in alkaline hydrothermal process to form composite material of reduced graphene flakes uniformly supporting titanium dioxide nanotubes modified by rhodium surface. USE - Method for preparing graphene-niobium-doped titania nanotube heterogeneous structure photocatalyst. ADVANTAGE - The photocatalyst has photocatalytic degradation efficiency reaching to 95.2%, wide spectrum of visible light response range, abundant surface active site, and higher charge separation capability.
