Colloidal iridium nanoparticles were prepared successfully by wet chemical way. The catalytic activity of these colloidal iridium nanoparticles was evaluated following the oxidation of alanine (Ala) by hexacyanoferrate(HCF)(III) in alkaline medium. These nanoparticles show a better catalytic activity than the iridium precursor. Easy recovery of the catalyst from the reaction mixture shows another positive significance.
