Different Ti/(I/S) composites were synthesized by sol-gel method and characterized by various techniques such as SEM, TEM, XRD, BET, and UV-Vis DRS. Among them, the 5-Ti/(I/S) composite showed significant photocatalytic activity towards rhodamine B, with a degradation rate of 81% and ·O-2(-) being the key oxidative species. Additionally, this composite exhibited good stability and repeatability.
Different Ti/(I/S) composites are synthesized by sol-gel method. The microstructure, interfacial and optical properties of the obtained different Ti/(I/S) composites are characterized by scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray diffraction (XRD), surface area measurement (BET), and UV-vis diffused reflectance spectroscopy (UV-Vis DRS). The results show that 5-Ti/(I/S) composite has an obvious photocatalytic activity to rhodamine B (RhB) and the degradation rate can reach 81%, center dot O-2(-) is the key oxidative species. Moreover, 5-Ti/(I/S) composite has good stability and repeatability.
