Abstract
Highly efficient Bi(2)WO(6)-TiO(2) heterostructures are synthesized by means of a hydrothermal method; they have high photoactivity for the degradation of rhodamine B under sunlike irradiation. An interesting synergetic effect between TiO(2) and Bi(2)WO(6) leads to an improved charge carrier separation mechanism, causing the excellent photocatalytic performance.
摘要
通过水热法合成了高效的 Bi(2)WO(6)-TiO(2) 异质结构，它们在模拟太阳光照射下对罗丹明 B 的降解具有很高的光活性。TiO(2) 和 Bi(2)WO(6) 之间的有趣协同效应导致了电荷载流子分离机制的改善，从而表现出优异的光催化性能。
