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%, ·O₂⁻ is the key oxidative species. Moreover, 5-Ti/(I/S) composite has good stability and repeatability.
