摘要：

Full employment of a Pt catalyst is reached by depositing very small (≤ 1.0 nm) Pt particles onto Au nanoparticles of about 10 nm in diameter (see picture) then loading the Pt∧Au particles onto a conventional carbon support. Data obtained from the electrooxidation of methanol demonstrate that every Pt atom assumes the function of an active site for electrocatalysis. (Figure Presented). © 2006 Wiley-VCH Verlag GmbH & Co.
