Enhancing by weakening: Electrooxidation of methanol on Pt₃Co and Pt nanocubes

(Figure Presented) Loaded dice: High-quality and similarly sized Pt ₃Co 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 Pt ₃Co nanocubes (see picture). The enhanced catalytic activity was explained by the slower and weaker adsorption of CO onto Pt₃Co.
