Synthesis of Tin-Doped Three-Dimensional Flower-like Bismuth Tungstate with Enhanced Photocatalytic Activity.

ABSTRACT: Photocatalytic degradation of harmful organic matter is a feasible and environmentally friendly method. Bi₂WO₆ has become a hotspot of photocatalysts because of its unique layered structure and visible light response. In the present study, Sn doping was adopted to modified Bi₂WO₆ by hydrothermal method. The Sn-doped Bi₂WO₆ photocatalysts were characterized by XRD, SEM, TEM, BET, XPS, PL, and DRS, respectively. The results show that Sn-doped Bi₂WO₆ shows three-dimensional (3D) flower-like morphology, which is composed of two-dimensional (2D) nanosheets. Sn⁴⁺ ions enter into the Bi₂WO₆ lattice, producing a degree of Bi₂WO₆ lattice distortion, which is
