摘要：

The electro-oxidation of dimethyl ether (DME), which is regarded as a promising alternative fuel for fuel cells, on platinum single-crystal electrode surfaces in acidic solution has been characterized by electrochemical and in situ IR observations. It has been found that the electro-oxidation behavior of DME depends significantly on surface structures. The (100)-terrace shows a particularly high activity in DME electro-oxidation in which C-O bonding is supposed to be selectively cleaved on the (100) terraces.
