摘　　要：以中性红为模板分子,γ-Fe2O3/Bi OCl/Bi VO4为载体,甲基丙烯酸为功能单体,乙二醇二甲基丙烯酸酯为交联剂,采用表面聚合的方法制备了磁性分子印迹型复合光催化剂,并对其进行表征和光催化特性的研究。实验结果表明:磁性分子印迹型光催化剂的比饱和磁化强度为6.37 emu/g,具有一定的顺磁性,能通过外加磁场有效地实现固液分离。光催化实验结果表明,无论单组分降解物还是多组分混合降解物,其都能优先选择降解其中的模板分子中性红。The molecule imprinted photocatalysts （MIP-T-Fe203/BiOC1/BiVO4 ）are prepared by surface polymerization method with neutral red as template molecule, γ-Fe2O3/BiOC1/BiVO4 as carrier, methaerylic acid as functional monomer, and ethylene glycol dimethylacrylic ester as cross-linking agent. The characterization and catalytic properties of samples are studied. The results show that the saturation magnetization of the samples is 6.37 emu/g, which can be effectively separated and recovered by using magnetic field. The photocatalytic results exhibit that for one-component and muhicomponent degradable materials,the targeted neutral red molecules both can be preferentially degraded.
