چکیده انگلیسی
- PdNP and Pd-H2NP catalyze reduction of [Fe(CN)6]3Â â with H2
- In presence of Pd-H2NP, reaction rate was ~Â 6-fold higher than that for PdNP.
- Pd and Pd-H2 is different in activity of dissociation of molecule H2 into atoms.
Palladium nanoparticles (5.3 ± 1.4 nm) catalyze the reduction of hexacyanoferrate(III) ions with hydrogen in aqueous solution. The reaction rate substantially (approximately 6-fold) increases if the nanoparticles are pre-saturated with hydrogen. The difference between the electronic properties of hydrogenated and non-hydrogenated palladium particles determines their activity in dissociation of the hydrogen molecule into atoms.
