Abstract

Palladium nanoparticles (5.3 ± 1.4 nm) catalyze the reduction of hexacyanoferrate(III) ions with hydrogen in an aqueous solution. The reaction rate substantially (approximately 5.5-fold) increases if the nanoparticles are pre-saturated with hydrogen. Presumably, the reaction rate is limited by the dissociative adsorption of hydrogen on palladium particles. The difference between the electronic properties of hydrogenated and non-hydrogenated palladium particles determines their activity in dissociation of the hydrogen molecule into atoms.

Keywords: catalytic reduction; palladium nanoparticles; hydrogen; potassium hexacyanoferrate(III).
