Cyclic voltammetry and chronoamperometry have been used to evaluate the electrochemical reactions taking place under SnO2/glass electrode polarization in a solution of Na2MoO4, H2SeO3, sodium citrate (C6H5Na3O7) and in solutions consisting of their mixtures. According to our study, the presence of a small concentration ofH2SeO3 in the electrolyte is necessary to induce the reduction ofMoO4 2 ions. Experimental data support an assumption that the reduction ofMoO4 2 ions to molybdenum could occur when selenium nuclei are initially formed on the electrode. Eventually selenium nuclei induce the electrodeposition of molybdenum, giving finally thin Mo–Se film layers. AAS analysis confirms that in the potential interval between –1.0 and –1.2 V, thin films with a Mo/Se atomic ratio 0.63 and 0.57, respectively, are obtained.
