| 摘 要： | 详细考察并比较了采用低温制备的锐钛矿、金红石和板钛矿氧化钛降解罗丹明B的光催化活性.与传统高温焙烧制备的金红石相比,低温制备的金红石粒径小,比表面积大,表面羟基数目多,因此光催化效率明显增加.更重要的是,当锐钛矿和金红石具有相似粒径和比表面积时,金红石具有较高的光降解罗丹明B活性.对于板钛矿氧化钛而言,虽然其表观光催化...

| Abstract: | This study compared the photocatalytic activities for the degradation of Rhodamine B (RhB) in aqueous solutions of anatase,rutile,and brookite TiO2.The TiO2 powders were prepared at low temperature.As compared with rutile obtained by a conventional high temperature calcination,the rutile TiO2 prepared by the low temperature route had a smaller particle size,higher surface area,and more surface hydroxyl groups,and it gave a high photocatalytic activity.Rutile gave a faster photocatalysis reaction rate than a... |
