Preparation of a Hybrid TiO2 and 1T/2H-MoS2 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 TiO2 and 1T/2H-MoS2 composite (1T/2H-MoS2/TiO2) 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-MoS2/TiO2 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.
