纳米四氧化三钴（Co3 O4）催化剂对废水中有机物具有良好的催化降解活性，但纳米催化剂难从溶液中分离的缺点限制了其应用。通过将不同量的纳米 Co3 O4催化剂自组装在纳米四氧化三铁（Fe3 O4）上，制备出了一系列不同纳米 Co3 O4催化剂含量的纳米 Fe3 O4/ Co3 O4，并将该系列纳米 Fe3 O4/ Co3 O4用于双氧水（H2 O2）氧化降解亚甲基蓝的反应来测试其催化性能和回收再利用性能。实验结果表明，尽管纳米 Co3 O4催化剂的含量对于纳米 Fe3 O4/Co3 O4的催化性能有所影响，但该系列纳米 Fe3 O4/ Co3 O4相对纯纳米 Co3 O4催化剂仍表现出很好的催化活性和回收再利用性。

Although the nano-Co3 O4 catalyst has good catalytic activity in the oxidation degradation of or-ganic compounds in waste water,its application is limited due to the difficulty in separation. In this study, a series of nano-Fe3 O4 / Co3 O4 are prepared through the immobilization of different loadings of nano-Co3 O4 catalyst on magnetic nano-Fe3 O4 nuclear. These nano-Fe3 O4 / Co3 O4 catalysts are used in the model reac-tion of oxidization of methylene blue by H2 O2 . The results of the oxidation reaction show that the loading of nano-Co3 O4 catalyst can affect the catalytic performance of the nano-Fe3 O4 / Co3 O4 ,and all of the nano-Fe3 O4 / Co3 O4 catalysts perform well in activity as well as recyclability with the help of additional magnet.
