Abstract :
Nanoporous gold electrodes were fabricated with a novel method: Silver-epoxy was painted on gold surface and Au-Ag alloy was formed by heating, then nanoporous structures were fabricated by dealloying process with nitric acid. The nanoporous gold electrodes shows high surface area (with a roughness factor of ~200) and high electrochemical activity. The electrooxidation of glucose on the nanoporous electrodes were investigated with electrochemical measurements.
