摘要:
以钛酸四丁酯为钛源,用溶胶凝胶法制备了改性累托石／TiO2光催化剂,运用X射线衍射和扫描电镜对其进行了表征.结果表明,累托石结构中负载了纳米TiO2.以300 W紫外灯为光源,以亚甲基蓝为目标降解物,得到制备交联钠化累托石/TiO2复合材料的最佳条件是盐酸浓度为0.2 mol/L,TiO2与累托石添加比例为5 mmol/g,复合材料的煅烧温度为500 ℃.研究了累托石／TiO2光催化剂的光催化性能,当用紫外灯光照20 min,反应温度为30 ℃,溶液pH为6时,亚甲基蓝的去除率达到90%以上.
Abstract:
Using tetrabutyl titanate as titanium source,Modified Rectorite/ TiO2 particle photocatalytic was prepared by SolGel method.XRay diffraction and SEM were used to characterize it. The results indicated that nanometer TiO2 was successfully prepared in the structure of Rectorite.The photocatalytic properties of Modified Rectorite/ TiO2 photocatalysts were studied by degradation of methylene blue under a 300 W ultraviolet light irradiation.Preparation of sodium rectorite / TiO2 composite optimal conditions are as follows: the concentration of hydrochloric acid is 0.2 mol/L, TiO2 added with a ratio of rectories 5 mmol / g, a calcination temperature of composite material is 500 ℃. We also study rectorite/TiO2 photocatalytic properties of light, When UV light radiates for 20 minutes,with the reaction temperature and 30 ℃ the solution pH 6, removal of methylene blue is over 90%.
