【摘要】 光催化剂的方便回收对于其降解有机污染物的应用是十分必要的.本项研究中,以硅酸钠为粘胶剂,在毛玻璃片上层层组装了多层磷掺杂TiO2粒子膜.扫描图片显示,厚度在几十微米的催化粒子膜牢固地覆盖在基片的粗糙面上.在太阳光照射5 h下,这样组成的复合体系几乎完全降解试验溶液中的亚甲基蓝;即使在循环利用10次以后,染料的降解率也高达70%以上.该研究表明,负载型磷掺杂TiO2纳米粒子膜具有优良的利用太阳光降解有机染料性能,并能较好地循环利用光催化剂.更多还原

【Abstract】 The convenient reuse of photocatalysts is essential to their practical applications in the degradation of organic pollutant.Compact P-doped TiO2 film coated on ground glass substrate was achieved by layer-by-layer assembly technique.Thus such an elaborate complex system exhibited very convenient in recycling photocatalyst in the degradation of dye.The excellent performance of P-TiO2 film coated on ground glass substrates endows the assembled route potential in purifying waste water.更多还原
