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。
Using the neutral red as the template molecule, γ-Fe2O3 / Bi OCl / Bi VO4 as the carrier, methacrylic acid as the functional monomer and ethylene glycol dimethacrylate as the crosslinking agent, the magnetic molecules were prepared by surface polymerization Imprinted composite photocatalyst, and its characterization and photocatalytic properties of. The experimental results show that the specific saturation magnetization of the magnetic molecularly imprinted photocatalyst is 6.37 emu / g and has a certain degree of paramagnetic property, which can effectively realize the solid-liquid separation by the applied magnetic field. The results of photocatalysis showed that no matter monocomponent degradants or multi-component mixed degradants, all of them could preferentially degrade the neutral red of the template molecules.
