Research progress on magnetic materials of magnetically separable photocatalyst

可磁分离光催化剂是一类具有磁响应特性的光催化剂。它不仅具有较高的光催化活性,而且在外加磁场作用下,容易分离回收。在参考近年来国内外光催化领域文献资料的基础上,概述了可磁分离光催化剂的命名和研究范围、磁载光催化剂的内部结构等内容。重点是根据磁载光催化剂的核壳之间是否包覆结合层,分别从直接包覆和非直接包覆两个方面,综述了近年来可磁分离光催化剂的磁载材料的研究进展状况,同时提出了目前磁载光催化剂研究的热点和发展趋势。

Magnetically separable photocatalyst is a new photocatalyst, which has magnetic response characteristic. This composite photocatalyst not only has high photocatalytic activity, but also can be separated and recovered easily under the extrinsic magnetic field. Based on the findings reported in the present literatures, this paper introduced the naming and researching scope of magnetically separable photocatalysts and the inner structure of magnetic photocatalyst etc. Meanwhile, according to the combining modes of central core and outside shell layers, this paper focused on reviewing the research progress on magnetic materials of magnetically separable photocatalyst in recent years from two aspects,i, e. direct coating and un - direct coating. Finally, the present research hotspot and development trend of magnetic photocatalysts were put forward.
