【 摘 要 】

Molybdenum disulphide nanoparticles having crystallite size of 5.55nm, were synthesized by low temperature hydrothermal method. X-ray Photoelectron Spectroscopy (XPS) was employed to probe into the energy levels of the synthesized Molybdenum disulphide nanoparticle. Findings of XPS suggest the presence of Mo6+, Mo4+ and Mo2+ oxidation states of Molybdenum 3d states. The Binding energy (BE) of sulphur was found to be 168.80 and 161.72 eV for S 2P1/2 and S 2P3/2 respectively, and the atomic percentage of Mo and S are in the ratio 1: 2.33, which patch up with the theoretical values.
