Abstract
MoS2 nanomaterial with diameter about 200nm was successfully synthesized by a facile hot-injection method, using molybdenum trichloride (MoCl3) and sulfur powder as the precursors. As-prepared MoS2 sample was characterized by X-ray diffraction (XRD) spectroscopy, scanning electron microscope (SEM), energy dispersive spectrometer (EDS) and X-ray photoelectron spectroscopy (XPS). The characterization results showed that the MoS2 sample possessed a pure phase. In addition, it was investigated by the degradation of rhodamine B (RhB) in aqueous solution to demonstrate the photocatalytic activity of the nano-MoS2. Photocatalytic results showed that the degradation rate of RhB could reach to 97% by the nano-MoS2 under visible light irradiation, which indicated that the morphology of the sample with a decent photocatalytic activity could donate some effects to the generation and transfer of the electron-hole.
