TiO2/HTiOF3 composites were made in a one step hydrothermal process for highly effective RhB degradation

In order to solve the pollution problem of organic pollutants in water, this study proposed a photocatalyst that efficiently utilizes sunlight, and TiO 2 /HTiOF 3 photocatalytic materials were successfully prepared by a hydrothermal method and used for the degradation of rhodamine B (RhB) solution under simulated sunlight. The effect of time and urea addition on the performance of the material was investigated, and the results showed that the sample with a reaction time of 12 h and a urea addition of 0.05 g exhibited 97 % degradation efficiency and the best photocatalytic degradation activity for RhB solution, which was attributed to the construction of a traditional type II heterojunction of the TiO 2 /HTiOF 3 nanocomposite, which improved the carrier separation rate and maintained a strong redox capacity. This work contributes to the construction of efficient semiconductor photocatalytic nano-heterostructures. The preparation of TiO 2 /HTiOF 3 composites by one-step hydrothermal method provides a new idea for the development of catalysts.
