普鲁士蓝纳米修饰电极的制备及表征

Preparation and Characterization of Prussian Blue Modified Nanoelectrode

采用激光加热拉伸法制备铂纳米电极,并通过交流电刻蚀制得纳米孔电极.在纳米孔电极上通过电化学方法原位合成普鲁士蓝微晶,并用扫描电子显微镜(SEM)、共聚焦显微Raman和循环伏安法对其表征.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.

Pt nanoelectrodes were fabricated by using a laser-based pipet puller and the recessed nanoelectro- des were prepared by etching of disk Pt nanoelectrodes with high frequency ac voltage. Prussian blue microcrystal was synthesized electrochemically on both disk and recessed Pt nanoelectrodes. The Prussian blue mierocrystal modified nanoelectrode showed a good solid-state cyclic voltammetric behavior. In this paper, a novel method for the controllable synthesis of single particles is proposed which has potential applications in modified electrodes and single particle electrocatalysis.
