| 摘 要： | 以硫酸钛为原料用水热法制备了掺Fe^3＋TiO2粉末,用SEM和XRD测定了样品的形貌和晶型,研究了以自制的掺Fe^3＋A-TiO2对甲基橙溶液的光催化降解作用。结果表明：所制备的TiO2为锐钛矿型TiO2即A-TiO2。365nm紫外光照射下,用自制的掺Fe^3＋A-TiO2降解甲基橙溶液的最佳条件是：10mg·L^-1的甲基橙溶液中加入0.050g掺5%Fe^3＋（物质的量比）A-TiO2粉末,用HNO3调节溶液成酸性后,18℃恒温反应4h,降解率达到57.8%。

| Abstract: | Fe3＋-doped TiO2 powders were prepared by hydrothermal method with titanium sulfate as raw materials and were charac-terized by means of XRD and SEM,and the degeneration of methyl blue photocatalyzed by as-prepared Fe3＋-doped A-TiO2 was studied.Experiment results show that the as-prepared TiO2 crystals are anatase TiO2（ie,A-TiO2）.The best degeneration rate of methyl orange is 57.8% under follow optimum conditions：adding 0.050 g as-prepared 5% Fe^3＋-doped（mole ratio）A-TiO2 powders into the 10 mg·L^-1 methyl orange solution which adjusted acidic by HNO3 illuminated by UV（λ=365 nm）,stirring quickly at 18 ℃ for 4 h. |
