Abstract
The use of semiconductor photocatalysts to degrade organic pollutants and convert them into useful chemical energy is a promising technology to solve environmental problems. MoS2 and TiO2 have matching band structures. In this work, detailed characterization showed that TiO2/MoS2 complexes were synthesized by the hydrothermal method. It effectively increases the separation rate of photogenerated electron-hole pairs. In this paper, the photocatalytic degradation of rhodamine B (Rh B) by TiO2/MoS2 composites with different proportions under visible light was studied. The results showed that the Mo/Ti ratio would affect the photocatalytic activity. The composite had the best catalytic performance when the Mo/Ti ratio was 2:1. Compared with the intrinsic TiO2, its degradation rate increased by 60.28%.
