Two types of polyoxometalate-functionalized magnetic nanoparticles catalysts consisting of H(3)PW(12)O(40) supported on surface-modified Fe(3)O(4) magnetite nanoparticles were prepared using an easy synthetic route and successfully applied for the oxidation of dibenzothiophene. The magnetic catalysts showed a catalytic performance in the oxidation of dibenzothiophene in acetonitrile with hydrogen peroxide, and high conversions were obtained. The catalysts could be easily separated from the reaction solution by applying an external magnetic field and recycled several times.
两种类型的多酸功能化磁性纳米粒子催化剂，由表面修饰的 Fe3O4 磁铁矿纳米粒子负载的 H3PW12O40 组成，通过一种简单的合成路线制备，并成功应用于二苯并噻吩的氧化反应。该磁性催化剂在乙腈中用过氧化氢氧化二苯并噻吩表现出良好的催化性能，可获得较高的转化率。通过施加外部磁场，催化剂可从反应溶液中方便地分离出来，并可重复使用多次。
