摘要
Different unsupported platinum nanoparticles are synthesized via water-in-oil microemulsion and colloidal methods (PAA). TEM, adatom adsorption and cyclic voltammetry measurements give very coherent results concerning the surface structure of the crystallites. The combination of these results with CO stripping experiments leads us to assign the oxidation peak multiplicity to surface structure rather than to pure size effect. (C) 2008 Elsevier B.V.
