Abstract

We demonstrate a seed-mediated growth of electrodeposited gold-nanoparticles (GNPs) onto a glassy carbon (GC) electrode from a solution of H[AuCl(4)] containing NH(2)OH at pH 0.5, resulting in a Au(111) facet ratio as high as 97%.

摘要

我们展示了一种通过在 pH 值为 0.5 的 H[AuCl(4)]溶液中加入 NH(2)OH，使电沉积金纳米粒子（GNPs）在玻璃碳（GC）电极上进行种子介导生长的方法，从而得到高达 97%的 Au(111)面比率。
