The Mo-doped Bi(2)WO(6) three-dimensional (3D) hierarchical microspheres from nanoplates have been synthesized by a hydrothermal route. The products were characterized in detail by multiform techniques: X-ray diffraction (XRD), energy-dispersive X-ray analysis (EDS), scanning electron microscopy (SEM), and UV-vis absorption spectrum. The results of the photocatalytic degradation of Rhodamine-B (RhB) in aqueous solution showed that molybdenum ions doping greatly improved the photocatalytic efficiency of Bi(2)WO(6) 3D hierarchical microspheres. The Mo-doped Bi(2)WO(6) microspheres with atomic ratio of Mo-W of 0.05 had the best activity in photodegradation of RhB in aqueous solution under 500 W Xe lamp light irradiation.
通过水热法合成了由纳米片组成的 Mo 掺杂 Bi(2)WO(6) 三维（3D）分级微球。通过多种技术对产物进行了详细的表征：X 射线衍射（XRD）、能谱（EDS）、扫描电子显微镜（SEM）和紫外-可见吸收光谱。在水溶液中光催化降解罗丹明 B（RhB）的结果表明，钼离子掺杂极大地提高了 Bi(2)WO(6) 3D 分级微球的光催化效率。在 500 W Xe 灯光照下，Mo 掺杂原子比为 Mo-W 0.05 的 Bi(2)WO(6)微球在水溶液中对 RhB 的光降解具有最佳活性。
