<span lang="EN-US">In this study, the tracing of the electroreduction process of molybdate ions in aqueous media at different conditions is achieved for obtaining molybdenum metal in a simple and easy way. The kinetics and the mechanism of the electroreduction of molybdate ions are studied using cathodic polarization technique. It is observed that, the speed of the electroreduction process depends on the speed of the change of the cathodic potential sweep as well as on the temperature of the electrodeposition bath. Moreover, it is observed that, at the potential range from the stationary potential (E_st = 0.25V) to −0.7 V, the electroreduction of molybdate ions occurs into two steps. Moreover it is observed that, after −0.7 V the electroreduction process of molybdate is accompanying with evolution of hydrogen.</span>

The electrolytic co-deposition of thin Mo-S semiconductive films from aqueous electrolytes has been studied. The potential region for electrolytic co-deposition of molybdenum with sulphur was determined with the technical drawing of cyclic polarization curves by the potentiodynamic method on Pt and Ni supports. Samples of electrolytic co-deposition of molybdenum with sulphur were also obtained using a galvanostatic method on Ni supports. X-ray phase analysis of the obtained samples indicated to the formation of chemical compound of MoS 2 composition.
