▎ 摘　　要

Nickel-loaded titanium dioxides with graphene oxide materials (NTG) were prepared using a two-step microwave-assisted method. These materials were used for the photodegradation of Rhodamine B under UV and visible irradiation. The role of nickel loading and the interactions between Ni, TiO2 and graphene oxide on the materials were investigated as a function of the Ni content. The interactions between Ni-Ti and graphene oxide at high Ni content resulted in a novel photocatalyst with fine adsorbility and high photocatalytic activity under visible irradiation. The best photocatalyst in the series, NTG-50 (50 wt% Ni loading) contained an interesting novel catalytic phase, NiTiO3, which is a well-known structure for visible light-driven photocatalytic reactions.
