【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。更多还原

【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.更多还原
