dc.description.abstract | The electrodeposition of rhenium and rhenium oxides from an alkaline aqueous solution containing
0.125 mol dm−3 NH4ReO4 + 0.01 mol dm−3 NaOH (pH 13.3 ± 0.1) has been studied. Cyclic voltammetry
studies were carried out using two electrodes, polycrystalline platinum and polycrystalline gold, and the
galvanostatic electrodeposition was conducted on a pure copper electrode (99.9%). Information regarding
rhenium electrodeposits has been obtained by means of scanning electron microscopy (SEM) and transmission
electron microscopy (TEM). The experimental results in an alkaline aqueous electrolyte suggest
that the electrocrystallization process follows a multi-step mechanism influenced by hydrogen adsorption.
The main conclusion was that rhenium, rhenium (IV) oxide and rhenium (VI) oxide coexist in the
electrodeposited material. | |
