摘要

摘要: 本文采用十六烷基三甲基溴化铵对钠基膨润土进行改性,并以有机改性膨润土作为载体,采用超声辅助溶胶-凝胶法制备了镧掺杂TiO₂/有机改性膨润土复合光催化材料,采用X射线衍射(XRD)、傅里叶变换红外(FT-IR)光谱和紫外-可见漫反射吸收光谱(DRS)等测试技术对其进行了表征分析,以TNT溶液作为目标物,考察了复合材料的吸附性能和光催化性能。结果表明:膨润土的有机改性抑制了TiO₂的晶粒生长,增强了复合材料的吸光性能,提高了复合材料的吸附和光催化性能。

Abstract: Lanthanum doped TiO₂/organic modified bentonite composite photocatalyst was prepared by ultrasonic-assisted sol-gel method, while the bentonite was modified by cationic surfactant cetyltrimethyl ammonium bromide. The micro-structure of the photocatalyst was characterized by means of X-ray diffraction, IR spectroscopy and Uv-Vis absorption spectroscopy respectively.The absorption performance, repeated recycled performance and photocatalytic performance of composite photocatalyst were studied by using TNT as mode organic pollutants. The results showed that organic modification can restrain the growing of TiO₂ grain size, increase the absorption intensity of composite photocatalyst, and enhance the photocatalytic performance of composite photocatalyst.
