Abstract
<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<sub>st</sub> = 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>

Summary
Molybdenum and its compounds are used in a wide range of different fields of industry.Molybdenum sulfide occupies a good and important position among the molybdenum compounds. The synthesis of MoS2 thin layers as photoelectrode material using the electrochemical method in different solutions were investigated [4,5]. For investigation the process of electrochemical synthesis of MoS2 thin film from aqueous solutions, at first it should be clarified kinetics and mechanism of the deposition process of the combination of the two components (Mo and S) from aqueous solutions on the cathode.
