Abstract

Electrodeposition of palladium has been investigated in a hydrophobic ionic liquid, 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide (BMPTFSI) ionic liquid containing a palladium halide complex, [PdCl 4]2- or [PdBr4]2-, at various temperatures. The diffusion coefficient of [PdCl4]2- at 25°C was ∼10-7 cm2 s-1, which was slightly smaller than that of [PdBr4]2-. The electrodeposits obtained from [PdCl4]2- were smoother and finer than those from [PdBr4]2-. The grain size of the electrodeposits was <40 nm even at 120°C, suggesting the crystal growth is suppressed in the ionic liquid. The current efficiency of the electrodeposition of palladium from [PdCl4]2- was <80%, probably due to the dispersion of palladium metal in the ionic liquid.
