Electrodeposition of palladium from palladium(II) acetylacetonate in an amide-type ionic liquid

The electrodeposition of palladium from palladium(II) acetylacetonate (Pd(acac)(2)) was investigated in an ionic liquid, 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)amide at room temperature. Potentiostatic cathodic reduction was conducted using a glassy carbon electrode at -2.0 V vs. Ag/Ag(I). Metallic palladium was deposited on the electrode and palladium nanoparticles were observed with dispersed state in the ionic liquid. The mean particle size of the obtained palladium nanoparticles was 2.8 +/- 0.6 nm. (C) 2015 Elsevier B.V. All rights reserved.
