| 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行。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。

| Abstract: | Nanocrystalline TiO_2 has been prepared 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 TiO 2 suspension indicate that the loading of TiO 2, initial pH and metal ions have obvious effects on the degradation rate. |
