Abstract:
The TiO2/posite photocatalyst was synthesized by two-step hydrothermal samples were characterized by X-ray diffraction, transmission electron microscopy, indicating that MoS2 has been essfully loaded on the surface of TiO2{101} a remarkable enhancement of photocatalytic activity was mainly attributed to the improved separation efficiency of photogenerated electron– hole pared with pure MoS2 particles and TiO2 nanospheres, TiO2/MoS2 posite photocatalyst has strong photocatalytic performance and good photocatalytic effect.
