摘要: Abstract Highly ordered Pd nanowire arrays were prepared by template-electrodeposition method using anodic aluminum oxide template. The arrays, in this paper, have high electrochemical active surface and show excellent catalytic properties for ethanol electrooxidation alkaline media. activity of oxidation is not only higher that film, but also than commercial E-TEK PtRu(2:1 weight)/C. micrometer sized pores channels act as structure units. They make liquid fuel diffuse into products out the catalysts layer much easier, therefore, utilization efficiency gets higher. are stable oxidation. may be a great potential direct cells sensors.
