Metal content and morphology of nanostructured Ag–Pd co-deposits
2012
Abstract Ag–Pd co-deposition on the surface of indium tin oxide coated glass (ITO-glass) by pulse electrolysis of solutions containing 0.01 M AgNO 3 and 0.01 M Pd(NO 3 ) 2 in dimethylformamide (DMF) has been studied at 20 °C. The nanostructured deposit is formed at pulse time ( τ on ) 6 ms and pause time ( τ off ) 300 ms within the range of − 0.5…− 1.75 V. About equimolar composition of the obtained Ag–Pd co-deposits, has been formed at cathode potentials higher than − 1.0 V; while before that potential value silver content is dominant. For the bimetallic Ag–Pd system formation of nanoclusters made of the single nanoparticles of about 20–30 nm particle size has been shown.
