  • In this study, TiO2/Cu2O/Pt composite hollow microspheres were prepared by precipitation and liquid deposition methods based on anatase TiO2 sol. The morphology and structure of different samples were controlled by different methods, the phase and structure, microscopic morphology, and optical properties of different samples were compared and analyzed. The results show that the introduction of Pt and Cu2O in the composites produces a syner-gistic effect, which effectively suppresses the electron- hole complexation, reduces the forbidden band width, and sig-nificantly enhances the light absorption in the visible region. Compared with TiO2, Cu2O and TiO2/Cu2O photocata-lysts, the TiO2/Cu2O/Pt photocatalyst had a significantly enhanced ability to degrade organic pollutants, can degrade 93% of methyl orange (MO) solution by 120 min of light, the degradation rate was 71% after four cycles, with excel-lent photocatalytic stability.
