Synthesis and study of structural and morphological properties of MoS2/Ag2S nanocomposites and investigating its photocatalytic properties

Abstract:   (1390 Views)
MoS2/Ag2S nanocomposite is synthesized by hydrothermal method without using inert atmosphere from green synthesized Ag nanoparticle. The synthesized samples were characterized and studied by X-Ray Diffraction (XRD), Fourier Transform-Infrared Spectroscopy (FTIR), Scaning Electron Microscope (SEM) and Transmision Electron Microscope (TEM) analysis. The optical properties of the samples were investigated by using UV-Vis absorption spectra. Also the formation of Ag nanoparticles via Sesbania sesban extract is confirmed by UV-Vis spectra. The hexagonal crystal structure of MoS2 and the monoclinic structure of Ag2S nanoparticles was confirmed by the result of X-ray diffraction pattern. SEM and TEM images showed the morphology and loading Ag2S on MoS2 structures. The photocatalytic activity of nanocomposite against of the methyl orange and methylene blue colors was evaluated by UV light. The results showed that the MoS2/Ag2S nanocomposite is a good destructive dye of methyl orange and to some extent methylene blue with UV light.
 
Keywords: Hydrothermal, nanocomposite, molybdenum disulfide, silver sulfide, photocatalytic activity.
