摘要

采用激光加热拉伸的方法制备铂纳米电极，并通过交流电刻蚀的方法制备纳米孔电极，在这两种电极上可通过电化学方法原位合成单颗普鲁士蓝微晶. 结果表明，普鲁士蓝微晶在纳米微孔电极上的机械附着强度增强. 这种方法可用于制备纳米修饰电极或研究功能微晶体材料的电化学性质.

Abstract

The Pt nanoelectrodes were fabricated by using a laser-based pipet puller and the recessed nanoelectrodes were prepared by etching of disk Pt nanoelectrodes wtih high frequency ac voltage. Prussian blue microcrystal was synthesized electrochemically on the both disk and recessed Pt nanoelectrodes. The strength of mechanical adhesion for the Prussian blue microcrystal on the nanoelectrode was enhanced. A novel method for the controllable synthesis of single particle is proposed, which has potential applications in modified electrodes and single particle electrocatalysis.

Key words： nanoelectrodes; recessed nanoelectrode; modified nanoelectrode; Prussian blue microcrystal; single particle
