【摘要】 <正>Recently, Dimethyl ether (DME) has attracted attention as a promising fuel in fuel cell. The electrochemical oxidation of DME on a polycrystalline electrode has been conducted recently by Shao et al. However, little work has been done on the electrochemical oxidation of DME on Pt single electrodes. Our aim is to find the different electrochemical oxidation characteristics of DME on Pt(110) and Pt(111) single crystal electrode. The Pt single crystal electrodes were prepared with J. Clavilier method. The electrochemical experiments were conducted in a standard three-electrode cell. Before cycle volammograms, the 0.5 mol L-1 H2SO4更多还原
