Abstract: The Ti3C2Tx/Bi2WO6 composites were prepared by hydrothermal method and were characterized by SEM, XRD, HR-TEM, UV-Vis DRS, PL and other techniques. The results show that Ti3C2Tx is dispersed into a sheet structure from the original accordion-like structure and inserted in Bi2WO6 with curly sheet structure. Acid fuchsin (AF) is used as a simulated pollutant to investigate the photodegradation effect of Ti3C2Tx/Bi2WO6. When the content of Ti3C2Tx is 7wt%, the photocatalytic activity of Ti3C2Tx/Bi2WO6 is better, and the AF degradation rate reaches 90.37% after 60 min of light irradiation. The stability of the Ti3C2Tx/Bi2WO6 is good as the AF degradation rate retains 80.91% after repeated use of the same photocatalyst for 4 times. The degradation mechanism shows that h+ and ·O2- are the main active substances for the degradation of AF.
