摘要
采用硬脂酸凝胶 (SAG)法制备了TiO2 纳米材料 ,用差热分析 ,热重分析 ,X射线衍射对合成过程进行了研究。用X射线光电子能谱 (XPS)对其表面状态进行了分析。TiO2 纳米材料对甲基橙溶液光催化降解结果表明 :催化剂浓度、初始溶液pH值和金属离子对降解效率有较大影响。
Nanocrystalline TiO2 has been prepared by using a stearic acid gel method, the synthesis was investigated by differential thermal analysis, thermogravimetric analysis and X-ray powder diffraction. The surface state was analyzed by means of X-ray photoelectron spectroscopy. The results of photocatalytic degradation of methyl orange in TiO2 suspension indicate that the loading of TiO2, initial pH and metal ions have obvious effects on the degradation rate.
