Other Pt Nanoparticles Unsupported and Supported

very close to the m value (= 2.6) found by a detailed layer model analysis. In addition, for the adsorption of the alkali metal elements (x 1), the prediction is that m 2, virtually the same m as obtained for clean surface Pt particles in an electrochemical environment. One would, therefore, expect that alkali adsorption does not significantly change the NMR spectrum of 

We have carried out NMR investigations of (conducting) carbon-supported Pt nanoparticles having an average particle size of
