摘要釆用原位沉淀法将CeO₂纳米颗粒附着在Bi₂₄O₃₁Br₁₀纳米薄片上制备CeO₂/Bi₂₄O₃₁Br₁₀复合半导体。利用SEM、XRD、HR-TEM、UV-Vis DRS、PL等技术对其进行表征。结果表明,CeO₂呈现纳米棒状颗粒分布在Bi₂₄O₃₁Br₁₀纳米片表面,形成异质结构;与CeO₂复合后,Bi₂₄O₃₁Br₁₀的UV-Vis吸收边发生了红移,增强了Bi₂₄O₃₁Br₁₀对可见光的响应强度,同时改善了Bi₂₄O₃₁Br₁₀的吸附性能。以氙灯作光源,酸性品红(AF)为模拟污染物,考察其光催化降解性能,光催化60 min时CeO₂/Bi₂₄O₃₁Br₁₀对AF的降解率达到97.6%, HPLC分析结果表明,AF最终降解成H₂O和CO₂。CeO₂/Bi₂₄O₃₁Br₁₀复合半导体具有良好的光催化稳定性,四次重复使用后,光催化60 min时CeO₂/Bi₂₄O₃₁Br₁₀对AF的降解率依然高达91.7%。光催化降解AF的机理探究结果表明,·O₂^-是光催化降解AF的主要活性物种。

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.
