Preparation of a Hybrid TiO 2 and 1T/2H-MoS 2 Photocatalyst for the Degradation of Tetracycline Hydrochloride.

Water pollution caused by antibiotics is a growing problem. Semiconductor photocatalysis is an environmentally friendly technology that can effectively degrade organic pollutants in water. Therefore, the development of efficient photocatalysts is of great significance to solve the environmental pollution problem. In this paper, mixed-phase TiO 2 and 1T/2H-MoS 2 composite (1T/2H-MoS 2 /TiO 2 ) were synthesized by the in situ growth method. The prepared compounds were characterized and applied to the visible-light degradation of tetracycline hydrochloride. The photocatalytic effect of 1T/2H-MoS 2 /TiO 2 on tetracycline hydrochloride is significantly enhanced under visible light and has good stability. It has potential applications in the treatment of organic pollutants in water.
