Preparation and Characterization of Visible-lLight-driven Sm-doped Bi2MoO6 Photocatalyst uUsed for Enhanced Degradation of Rhodamine B

Bi2MoO6 samples containing different weight contents of Sm dopant as the visible-light-driven photocatalyst were successfully synthesized by hydrothermal method. All of them were certified as orthorhombic Bi2MoO6 nanoplates. The visible-light absorption range of Bi2MoO6 was increased by increasing in the Sm dopant. Different weight contents of Sm dopant containing in Bi2MoO6 were studied through the degradation of rhodamine B (RhB) under visible light irradiation. The photocatalytic efficiency of 1% Sm doped-Bi2MoO6 nanoplates was the highest of 96.27% or 3.91 times of Bi2MoO6 (24.65%) by increasing specific surface area, visible light harvest and separation of charge carriers. Highlights Visible-light-driven Sm-doped Bi2MoO6 photocatalysts were synthesized by hydrothermal method. Pure phase of Sm-doped Bi2MoO6 nanoplates was produced in this research. The photocatalytic reaction of samples was tested by rhidamine B (RhB) degradation under visible light irradiation. 1% Sm-doped Bi2MoO6 showed the highest photocatalytic performance in this research.
