摘要： 采用溶胶-凝胶法制备了 5-(对-烯丙氧基)苯基-10,15,20-三对氯苯基卟啉(APTCPP)敏化的 TiO2 复合微球 APTCPP- MPS- TiO2. 运用紫外-可见光漫反射吸收光谱、热重分析、X 射线衍射、光电子能谱和扫描电镜等手段对 TiO2 复合微球进行了表征. 考察了复合微球在可见光照射下对α-松油烯的光催化氧化活性. 结果表明, 复合微球中 TiO2 主要以锐钛矿晶型存在, 微球粒径约为 0.7~1 μm. 卟啉的加入有效提高了 TiO2 复合微球对α-松油烯的光催化活性, 催化氧化产物主要是土荆芥油素.

Abstract: Novel porphyrin-sensitized TiO2 microspheres (APTCPP-MPS- TiO2) were prepared by a sol-gel method and characterized. The photooxidation of α-terpinene was used to evaluate the photocatalytic activity of APTCPP-MPS-TiO2 microspheres under visible light. The microspheres had excellent catalytic activity and stability.
