We report the synthesis of Pt nanoparticles stabilized through the addition of molybdate. The resultant particles were smaller than uncapped Pt particles with average sizes in the 7.5-8.4 nm range. Evidence for an interaction between molybdate and platinum comes from energy-dispersive X-ray spectroscopy, XPS and CV measurements. The voltammetric features of the molybdate-stabilized Pt particles indicated an electrochemically accessible surface. Incorporation of additional molybdate and acid to the synthesis bath leads to post-synthetically modified Pt nanoparticles which feature a partially oligimerized molybdate overlayer.
