摘　　要：纳米TiO_2的光催化降解作用效率高,但存在回收困难的问题。用超顺磁性和耐腐蚀的铁磁性微粒作为载体,制成磁性包覆型纳米光催化剂既有普通悬浮光催化剂的高效性,又能通过磁性顺利收集,克服了悬浮状粉末回收困难的缺点。本文通过溶胶-凝胶方法将TiO_2材料包覆在磁性粒子Fe_3O_4表面,制备在外界磁场下可被回收循环利用的光催化材料,并对材料光催化模拟性能进行分析。The effect of nano TiO2 photocatalytic degradation efficiency is high,but the recovery is very difficult.With superparamagnetic iron magnetic particles and corrosion resistance as a carrier,we made of magnetic coating type nano photocatalyst.It not only has the efficiency of ordinary suspended photocatalyst,but also is collected easily through the magnetic,overcomes the difficulty of suspending TiO2 powder recovery.The TiO2 material is made in coating on the surface of Fe3 O4 particles by sol gel method.It can be recycled in the external magnetic field,and analysis the properties of material photocatalytic simulation.
