摘要：

(Figure Presented) A change in orientation of adsorbed oxygen molecules from parallel (top) at the bare Pt electrode to a mixture of parallel and end-on modes at a Pt surface modified by the electrodeposition of manganese oxide nanoparticles (nano-MnOx/Pt) causes a higher population of oxygen molecules at the MnOx/Pt surface (bottom). The modified electrode is thus a superior electrocatalyst for the reduction of oxygen (Pt yellow, O white, MnOx black). © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
