Morphology and photocatalytic activity of TiO2/MXene composites by in-situ solvothermal method

In this work, TiO2/MXene composites were successfully synthesized through an in-situ solvothermal method, where the morphology of TiO2 nanoparticles (NPs) was modified by different concentrations of agents. Ti3C2Tx with electronic storage characteristics was employed as a co-catalyst to enhance the photocatalytic degradation activity by capturing photogenerated electrons. The experimental results reveal that, with the help of C3H8O agents, TiO2 NPs are uniformly distributed on the surface of Ti3C2Tx. The TiO2/Ti3C2Tx-C3H8O composite showed the highest photocatalytic activity of 90.5% after 75 min under mercury light irradiation, which is 57.9% higher than that of the pure TiO2 photocatalyst. The photocatalytic activity is promoted due to the high photoelectron transmission performance of the TiO2/Ti3C2Tx composites.
