Abstract
BiFeO3 perovskite with 2D laminated cylinder-like structure was prepared via a facile one-pot hydrothermal method, whose morphologies and optical properties was characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersion spectrum (EDS), and UV-Visible diffuse reflectance spectroscopy (UV-Vis DRS). The photocatalytic properties of the as-prepared BiFeO3 composites were evaluated according to degrading Rhodamine B (RhB) and desulfurization under visible light irradiation, with excellent photocatalytic degradation and desulfurization activity found. Moreover, the mechanism study of active free radicals in photocatalytic activity indicates that the h+ radical in holes was mainly responsible for synergistic catalytic efficacy in photocatalytic degradation.
