Synthesis, electrochemical properties, and photocatalytic investigation of MoS۲

Transition metal disulfides MS۲ (M = Mo, Ti, W, and V) constitute an important class of inorganic layered compounds. Due to the unique properties, MS۲ nanostructures with sheet-like morphology have been emerging as new potential materials for several applications such as catalysis, transistors, hydrogen storage, solid lubricants, Li-ion batteries, and double-layer capacitors. The MoS۲ nanoparticles were synthesized by hydrothermal method. Degradation of dyes with nanoparticles has attracted great attention these days. The flower-like MoS۲ nanosheets were synthesized by hydrothermal method using a thio Schiff base ligand as a sulfur source and simultaneously as a capping agent. In the study of photocatalytic activity. The X-ray diffraction (XRD) pattern reveals the monoclinic structure of MoS۲ nanoparticles. The UV-visible absorption spectrum was in the wavelength range of ۲۵۰-۸۰۰ nm and the band gap was calculated from Tauc Plot. The Surface morphology of synthesized materials was observed by Field Emission Scanning Electron Microscope (FESEM) and Transmission electron microscopes (TEM).
