Abstract
The main purpose of the research was to obtain bimetallic nanodeposits by a simple electrochemical method. Gold and palladium were chosen as the objects for simultaneous electrodeposition. Gold–palladium deposits were obtained by pulse potentiostatic electrolysis on a glassy carbon surface in dimethyl sulfoxide solution with (0.001–0.004)M HAuCl4, 0.004M PdCl2 and 0.05M Bu4NClO4 at the constant temperature of 35°C. The bimetallic nanoparticles were found in the potential range of –(0.3–1.5)V vs Ag/AgCl in saturated KCl during pulse time of 6ms and pause of 300ms. Increase in the potential value resulted in higher palladium content in the deposits. Depending on the electrodeposition time discrete bimetallic nanoparticles transformed into complete nanostructured films made of gold and palladium.
