摘要

提出了一种制备纳米孔金电极的新方法:在金表面涂上环氧银，加热形成金-银合金，再用硝酸合金化法制备纳米孔结构。纳米孔金电极具有高表面积(粗糙度系数约为200)和高电化学活性的特点。用电化学测量方法研究了葡萄糖在纳米孔电极上的电氧化。

Facile fabrication of nanoporous gold electrodes that demonstrate high electrochemical activity and used for glucose electrooxidation

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.
