Abstract CeO₂/Bi₂₄O₃₁Br₁₀ composite semiconductors were prepared by attaching CeO₂ nanoparticles to Bi₂₄O₃₁Br₁₀ nanosheets via in situ precipita-tion method, and characterized by SEM, XRD, HR-TEM, UV-Vis DRS, PL and other techniques. The results showed that nanorod-like CeO₂ particles were evenly distributed on the surface of Bi₂₄O₃₁Br₁₀ nanosheets, forming heterojunction structures. After combined with CeO₂, the UV-Vis absorption edge of Bi₂₄O₃₁Br₁₀ red-shifted, which enhanced the visible light response of Bi₂₄O₃₁Br₁₀ and meanwhile improved the adsorption performance of Bi₂₄O₃₁Br₁₀. The photocatalytic performance of CeO₂/Bi₂₄O₃₁Br₁₀ was investigated via photocatalytic degradation of acid fuchsin (AF) with xenon lamp as the light source. The result indicated that the degradation rate of AF reached 97.6% after 60 min light irradiation. HPLC analysis results showed that AF was finally degraded to H₂O and CO₂. CeO₂/Bi₂₄O₃₁Br₁₀ composite semiconductor has good photocatalytic stability as the degradation rate of AF retained 91.7% after 4 times of reuse of the same photocatalyst. The photocatalytic mechanism study revealed that ·O₂^- was the main active species in photocatalytic degradation of AF.
