PbMoO 4 -coated carbon microspheres (CMSs@PbMoO 4 ) were synthesized by a multistep method using CMSs as a support. In this synthesis dispersed CMSs were prepared by a hydrothermal method using glucose as a carbon source and used as an absorbent and support coated by PbMoO 4 at room temperature. The as-prepared CMSs@PbMoO 4 was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR). The photocatalytic activity of the as-prepared sample was evaluated by degradation of Rhodamine B in aqueous solution under visible light irradiation. The CMSs@PbMoO 4 show effective photocatalytic activity. In addition, the photocatalytic mechanism of CMSs@PbMoO 4 was proposed.
