| 中文摘要: |
| 以Ti(SO4)2酸溶液为前驱体．氢氧化钠作沉淀剂，采用沉淀法低温焙烧制备了SO4^2-掺杂的金红石型TiO2微粒．用光催化降解正庚烷为反应模型．结合BET、TG-DTA、IR、XRD等表征手段，探讨了制备条件对金红石型SO4^2-／TiO2微粒气相光催化活性的影响，并优化实验条件获得了光催化性能优良的金红石型SO4^2-／TiO2微粒． |
| 英文摘要: |
| Rutile SO_4~(2-)/TiO_2 particles were prepared via precipitation method by using Ti(SO_4)_2 acid solution as precursor and NaOH solution as precipitant and calcined at low temperatures. Based on the characterizations such as BET, TG-DTA, IR and XRD, the effect of preparation conditions on the gaseous photocatalytic activity of rutile SO_4~(2-)/TiO_2 was discussed through the photodegradation of heptane. The experimental conditions were optimized to obtain rutile SO_4~(2-)/TiO_2 particles with higher photocatalytic activity. |
