Abstract: <DIV>Abstract：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. </DIV>Key words：magnetic separation；TiO2；photocatalyst；coating
