Hydrothermal synthesis and characterization of visible-light-driven 0–3 wt % Br-doped Bi₂MoO₆ photocatalysts

Abstract

0–3 wt % Br-doped Bi₂MoO₆ samples as visible-light-driven photocatalysts were successfully synthesized by hydrothermal method. The Br-doped Bi₂MoO₆ samples were characterized by X-ray diffraction, transmission electron microscopy and X-ray photoelectron spectroscopy. In this research, the as-synthesized samples were specified as the orthorhombic Bi₂MoO₆ phase with very high crystalline degree. The 3 wt % Br-doped Bi₂MoO₆ sample shows the best photocatalytic degradation of rhodamine B and its photocatalytic performance follows the first order kinetics model under visible light irradiation.
