摘要：
In this study, B-doped titania hollow spheres were prepared using hydrothermally prepared carbon spheres as template. The photocatalytic activity of as-prepared hollow titania spheres was determined by degradation of Reactive Brilliant Red dye X-3B (C.I. reactive red 2) under visible light irradiation, and was compared to commercial P25 titania. It was revealed that the photocatalytic activity of the hollow titania spheres enhanced a lot. The apparent rate constant of the hollow titania spheres was almost 22 times as that of P25 titania. A photocurrent-time spectrum was also applied to investigate the efficiency of electron transfer in the process of photocatalysis reactions by different samples. (C) 2009 Elsevier B.V.
