Abstract

Platinum nanocubes with preferential {1 0 0} surfaces are synthesized by colloidal method and characterized by TEM image and hydrogen adsorption/desorption process. The mean diameter of Pt nanocubes is ca. 10.5 nm. The hydrogen adsorption/desorption wave shows clearly the <1 0 0> preferential orientation. It is proved that dimethyl ether oxidation on Pt nanocubes exhibits similar features with bulk Pt single crystal electrode. The catalytic activity of Pt nanocubes for DME electro-oxidation is nearly 3× higher than that on commercial available Pt black catalyst. After potential step to 1.2 V, the surfaces of Pt nanocubes are reconstructed and the activity for DME electro-oxidation decreases.
