Abstract

Pt(0) nanoparticles stabilized by the H₅PV₂Mo ₁₀O₄₀ polyoxometalate were prepared in water by a sequence of redox reactions and supported on α-alumina. Characterization by TEM showed an average particle size of 2.6 nm with an approximate size dispersion of about ±25%. EDS analysis confirmed the amounts of metal and polyoxometalate as indicated from the reaction stoichiometry. These nanoparticles were further used as catalysts for the oxidation of secondary alcohols with molecular oxygen to the corresponding carbonyl products. The oxidation of secondary alcohols was further improved by the use of Pt nanoparticles stabilized by Rh_1.7PV₂Mo₁₀O ₄₀.
