摘要
The novel few-layers MoS2 sensitized Ag-TiO2 were prepared through hydrothermal method, photoreduction method and spin-coating method, respectively. The microstructure, surface morphology, chemical composition and ultraviolet-visible absorbance of the samples were investigated systematically. The results indicated that the Ag nanoparticles and few-layers MoS2 were deposited successfully on the surface of TiO2 NRAs. The visible photocatalytic activity was estimated by degradation of methylene blue solution. The results indicated that the photocatalytic properties of MoS2/Ag-TiO2 was larger than pure TiO2 NRAs and Ag-TiO2. The significantly increased photocatalytic properties was attributed to the stronger visible light capture capability and the enhanced electron-hole pairs separation.
