| 摘 要： | 本文针对传统方法合成TiO2/SBA-15的诸多不足,提出了一种简单而快速合成TiO2/SBA-15的方法。利用孔道内水解法快速合成了不同负载量的TiO2/SBA-15。利用XRD、N2-吸脱附、TEM和UV-Vis对样品的晶体结构、微观形貌、光学吸收特性进行了表征,并研究了不同TiO2负载量催化剂对罗丹明B(RhB)光降解活性的影响。结果表明:利用该方法合成的TiO2/SBA-15光催化活性优于传统浸渍方法合成的TiO2/SBA-15与工业上使用的TiO2纳米颗粒。

| Abstract: | A rapid internal hydrolysis method was developed for the synthesis of TiO2/SBA-15. The as-synthesized material was characterized by XRD, N2 adsorption-desorption, TEM and UV-Vis techniques. The photodedegradation of Rhodamine B(RhB) in aqueous medium was selected as a probe reaction to evaluate the photocatalysis performance of TiO2/SBA-15. The influence of TiO2 loading on the photocatalysis performance was also studied. The photocatalysis performance of TiO2/SBA-15 is better than that of pure TiO2 and TiO2/SBA-15 by impregnation method. |
