中文摘要：
应用激光加热拉伸法制备金纳米电极,研究了非金属物种氧和碘在金纳米电极表面的吸附以及金属铅和铜在金纳米电极表面的欠电势沉积行为,观察到吸附物种在金纳米电极上显著的表面扩散现象.
英文摘要：
Gold nanoelectrodes were prepared successfully by a programmed laser puller.The Faraday adsorptions of oxygen and iodine,and the underpotential deposition of lead on the gold nanoelectrodes were investigated.The results showed that the active areas of nanoelectrodes were dramatically higher than their apperant geometry areas,which is caused by the surface diffusion of adsorptive species from the nanoscale gold/electrolyte interface to the adjacent gold surface.
