| 摘 要： | 以硅胶为载体,用浸渍法制备了Fe3+-TiO2/SiO2光催化剂,XRD、Raman分析结果表明TiO2为锐钛矿晶型,光催化实验表明,铁离子掺杂量X(Fe3+/Ti4+)=0.5%时,乙醛光催化降解率最高,水气的存在使Fe3+-TiO2/SiO2活性增加,动力学研究表明,光催化降解气相中乙醛的动力学可以用Langmuir-Hinshelwood动力学方程描述.

| Abstract: | The Fe3+-TiO2/SiO2 thin film photocatalysts are prepared by means of impregnation method. The degradation ratio of the catalyzed acetaldehyde is highest while iron ion doping concentration is 0.5%. The results studied by XRD and Raman technologies indicate that the TiO2 crystal is an anatase phase. The photocatalytic degradation rate will increase along with the increase of water vapor. The kinetic regularity of the photocatalytic degradation of acetaldehyde in gas phase is predicted. It is in good agreement with the Langmuir-Hinshelwood model. |
