A study was conducted, to demonstrate that a self-supported nanoporous gold film (NPGF) can be used for highly effective direct electro-oxidation of methanol in alkaline solution at room temperature. The self-supported NPGF electrode was fabricated through multicyclic electrochemical alloying, or dealloying of a polished gold electrode in an electrolyte composed of ZnCl 2 and benzyl alcohol (BA). It was found that the activity of NPGF was about 400 times more than that of the smooth gold electrode without decreasing after 100 cycles of activity...
