%X S-doped Bi 2MoO 6 nanosheets were successfully synthesized by a simple hydrothermal method. The as-prepared samples were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscopy (TEM), N 2 adsorption¨Cdesorption isotherms, Raman spectroscopy, Fourier transform infrared spectroscopy (FT-IR), elemental mapping spectroscopy, photoluminescence spectra (PL), X-ray photoelectron spectroscopy (XPS), and UV-visible diffused reflectance spectra (UV-vis DRS). The photo-electrochemical performance of the samples was investigated via an electrochemical workstation. The S-doped Bi 2MoO 6 nanosheets exhibited enhanced photocatalytic activity under visible light irradiation. The photo-degradation rate of Rhodamine B (RhB) by S-doped Bi 2MoO 6 (1 wt%) reached 97% after 60 min, which was higher than that of the pure Bi 2MoO 6 and other S-doped products. The degradation rate of the recovered S-doped Bi 2MoO 6 (1 wt%) was still nearly 90% in the third cycle, indicating an excellent stability of the catalyst. The radical-capture experiments confirmed that superoxide radicals (£¿O 2£¿) and holes (h +) were the main active substances in the photocatalytic degradation of RhB by S-doped Bi 2MoO 6.
