Studying the electrochemical deposition process of molybdenum from aqueous solution of molybdate ions

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>

CO-ELECTRODEPOSITION OF THIN Mo-S FILMS

“…The electrochemical reduction processes of molybdenum [6] and sulfur [7] were studied separately to determine the potential region, deep reduction, and the nature of polarization for carrying out joint electrochemical deposition, as described above.…”

“…As you know, to obtain thin films of semiconductor materials by co-deposition, the first need to do is to study the kinetics and mechanism of the electroreduction process of the components separately. This was investigated by us in [6,7].…”

Electrodeposition of the Sb2Se3 thin films on various substrates from the tartaric electrolyte

“…To obtain high-quality Sb 2 Se 3 thin films with an electrochemical method, more accurate experimental results in this field of research are still required. This work is a part of our systematic investigation in the area of electrodeposition of thin films of semiconductor chalcogenides [31][32][33][34][35][36][37]. Therefore, the present contribution is devoted to exploring the optimal conditions for obtaining high-quality films of antimony selenide via studying the effect of the substrate material on the electrodeposition process.…”

Investigation of the Electrochemical Reduction Process of the Molybdate Ions in the Tartaric Electrolytes

“…The following up of the electroreduction process of the molybdate ions in an aqueous medium under different conditions was achieved to obtain the metallic molybdenum. 15 The kinetics and the mechanism of the electroreduction process were studied by the cathodic polarization. It was observed that the rate of the electrochemical process depends on the scan rate of potential, and the temperature of the electrolyte.…”
