Abstract: CsxWO3/TiO2 composites with full-spectrum catalytic activity were prepared by solvothermal reaction. The composites were characterized using X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM), transmission electron microscopy (TEM), specific surface area testing, X-ray photoelectron spectroscopy (XPS), and UV-Vis diffuse reflectance spectra (UV-Vis DRS). CsxWO3 and TiO2 were uniformly bonded together in the composites. The heterojunction structure was formed. The band gap was reduced from 2.75 to 2.65 eV. The photocatalytic property of CsxWO3/TiO2 was demonstrated by the degradation rates of 20 mg·L-1 methylene blue dye, which were 99.7%, 91.4%, and 70.7% under irradiation from a 300 W high-pressure mercury lamp, a 500 W xenon lamp, and a 400 W infrared lamp, respectively. After five cycles of photocatalytic degradation, the composite photocatalyst still showed a degradation efficiency of 87.6%. This indicates that CsxWO3/TiO2 has good photocatalytic degradability and cyclic stability. The photocatalytic mechanism of CsxWO3/TiO2 was investigated. The trapping experiments of the active species showed that the main active substances were the empty hole (h+) and hydroxyl radical (·OH).
