Abstract Scope |
Palladium electrodeposition in ionic liquid (IL) is considered a promising alternative to aqueous electrolytes because of some unique properties, such as exceptional chemical stability, wide electrochemical window, and low volatility. In the present work, the electrodeposition was performed by using 1-ethyl-3-methylimidazolium chloride [EMIM-Cl] IL as the electrochemical bath in order to investigate the morphology of deposited palladium. Glassy carbon served as working electrode in the rotating disk technique. After identifying the cathodic and anodic potentials of interest by using cyclic voltammetry, the working electrode was taken out at each of these potentials and prepared for characterization by SEM. It was discovered that two cathodic waves are driven by same reduction of PdCl42- reaction. Smooth Pd filming happens during the first, while growth of Pd aggregates (on Pd film) signifies the second cathodic wave. The effects of rotation on the morphology of palladium was also examined. |
