Enhancing by Weakening: Electrooxidation of Methanol on Pt₃Co and Pt Nanocubes

Abstract

Loaded dice: High-quality and similarly sized Pt3Co and Pt nanocubes were prepared by gradually reducing metal precursors at high temperatures. Cyclic voltammetric and chronoamperometric results show a much higher methanol oxidation current density on Pt3Co nanocubes (see picture). The enhanced catalytic activity was explained by the slower and weaker adsorption of CO onto Pt3Co. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
