In this research, a new mechanochemical route has been introduced for solid-state reduction of MoS2 using metallic Zn powder as reductant. Nano particles of Mo and ZnS were synthesized as final product. When MoS2 and Zn were used as the starting mixture, the reaction was completed after 12 h. Whereas this reaction was completed after 5 h and 8 h of milling in presence of Al2O3 and CaO respectively. In this research X-ray powder diffraction (XRD) was employed for studying the reactions’ progress. Scanning electron microscopy (SEM), transmission electron microscopy (TEM), and laser particle size analyzing techniques were employed for studying the morphology and size distribution of the ball-milled powders. Results have shown that decreasing in size of particles in presence of Al2O3 and CaO was the main reason of improving kinetic of the reaction.
