摘要
以多孔基质为载体;用溶胶—凝胶法制备出载TiO_2薄膜的多孔型光催化剂。用X射线衍射和扫描电镜对催化剂的物相和形貌进行了表征。此催化剂能在光照下分解水溶液中四环素抗菌素。经1h光照,四环素的分解率可达85％左右。
Taking porous matrix as carrier to prepare porous type photocatalyst of TiO2 membrane by sol-gel technique. The phase and shape were determined by XRD and SEM. The photocatalyst could photo-decompose tetracycline antibiotic of aqueous solution. The photolytic rate could be maintained at 85% through various UV irradiation for Ih.
