Visible light Bi2S3/BiFeO3 photocatalyst for effective removal of Rhodamine B

Visible light Bi2S3/BiFeO3 photocatalyst for effective removal of Rhodamine B

Bi2S3-sensitized BiFO3 (BFO) photocatalyst (Bi2S3/BFO) was successfully synthesized through a facile and environmental ion exchange method between BFO and Thiosurea (H2NCSNH2, TU). The photocatalysts were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive...
