摘要：以Fe₃O₄为磁核，制备了易于分离的磁性光催化剂。采用X射线粉末衍射(XRD)、扫描电镜(SEM)、光电子能谱(XPS)、傅里叶红外光谱(FTIR)等手段表征催化剂的表面形貌、晶型组成、化学结构等。结果表明，TiO₂包覆在Fe₃O₄表面，且包覆较为牢固。利用降解斯蒂酚酸考察其光催化性能，制得的催化剂具有较高的光催化活性和较好的可分离性。

Abstract：Magnetic photocatalysts (TiO₂/ Fe₃O₄), which are liable to be separated and recovered, were prepared using Fe₃O₄ as the support. The surface morphology and crystal pattern were investigated by means of XRD, SEM, XPS and FTIR. The results showed that TiO₂ wraps on the surface of Fe₃O₄. The photocatalytic activity of the catalysts was investigated by photocatalytic decolorization of (TNR). The photocatalytic activity of the catalysts is high and the separating ratio is good.
