摘要：

Electrochemical dehydrogenative oxidation of cyclohexane to benzene is studied over Pt and Pt1Rh1 nanowire electrocatalysts fabricated by electrospinning method, which shows the higher catalytic activities in a polymer electrolyte membrane fuel cell anode than the conventional Pt nanoparticle catalysts such as carbon-supported Pt or Pt black. The improved performances over the Pt1Rh1 nanowire electrocatalyst can be rationalized by enhanced electrical property and pertinent interface formation with nanowire catalysts in the high Pt-loaded cyclohexane fuel cell system.
