中文摘要：通过溶胶-凝胶法(sol-gel),以钛酸四异丙酯和Tb2O3为前驱体制备出一系列不同掺铽量的TiO2柱撑膨润土(Tb-TiO2-PILCs)。采用XRD、BET测试技术对制得的复合催化剂进行了表征。并以五氯酚钠为目标污染物,考察了它们的光催化性能。结果表明,掺铽与未掺铽的Ti02-PILCs中TiO2主要以锐钛矿型存在;掺铽的Tb-TiO2-PILCs的光催化活性明显优于未掺铽的TiO2-PILC,Tb/Ti质量比为0.5%的Tb-TiO2-PILC催化活性最佳。复合催化剂具有回收容易,重复使用性好等特点。

外文摘要：The terbium doped TiO2 pillared bentonites （Tb-TiO2-PILCs） were prepared and Tb2O3 as precursors by the sol-gel method. Characteristics of Tb-TiO2-PILCs were and BET. Tb-TiO2-PILCs were used as composite photocatalysts for the photocatalytic d with Ti （ i-C3H7O ） 4 examined with XRD egradation of sodium pentachlorophenate （PCP-Na）. The results indicate that all the pillared bentonites contain TiO2 in the anatase phase. The photocatalytic activities of Tb-TiO2-PILCs are superior to that of non doped TiO2-PILC. Tb-TiO2- PILC shows the most photocatalytic activity when the mass percent of Tb/Ti is 0. 5% among all the catalysts. In addition, the experiments also illustrate that the composite photocatalysts can be easily recovered, regenera- ted and reused.
