    Journal: J Hazard Mater; 2011 Aug 15; 192(1):186-91. PubMed ID: 21664048.
    Abstract:
    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.
