The Effect of Pt Loading on Catalytic Activity of Pb@Pt/C Nanocomposites Toward Ethanol Oxidation.

Here, we study the influence of the Pt loading and the particle size of Pb@Pt/C catalysts on their specific activity toward ethanol oxidation in acid media. High angle annular dark field-scanning transmission electron microscopy and electron energy loss spectroscopy data indicate the formation of Pb@Pt/C core-shell structures, which are well dispersed on carbon support, with spherical shapes and small particle sizes (2.9-6.
