中文摘要：以氯化铁为起始原料,制备得到了高磁性的立方块型纳米四氧化三铁,然后对所得到的四氧化三铁表面用二氧化钛进行修饰,优化条件得到TiO2/Fe3O4复合催化剂,并通过透射电镜、XRD、紫外-可见光分光光度计和物性测试系统等仪器对所得到的催化剂进行详细地表征。优化得到的复合物催化剂对罗丹明B紫外光下的降解效率达到85%,在太阳光下降解率可达68%,且催化剂可以方便地经磁性分离回收。

外文摘要：The nano cube type ferroferric oxide with high magnetic was synthesized with ferric chloride as starting materials.Then the surface of ferroferric oxide was modified with titanium dioxide and the TiO2/Fe3O4 composite catalyst was obtained with optimized conditions. The obtained catalysts were characterized by TEM,XRD,UV-Vis spectrophotometer and physical properties measurement system.The degradation efficiency of Rhodamine B was 85% under UV irradiation and 68% with sunlight.The catalyst could be recovered easily by magnetic separation.
