摘要: 同种材料而表面结构不同的电极往往有完全不同的电化学性能.使用在原子水平上表面结构明确的单晶电极不仅有助于对电极表面吸脱附过程、电场作用下表面结构重组、双电层微观结构、分子水平上的反应机理等基础理论进行深入研究,且对高选择性、高效电催化剂的研制也有指导意义.单晶电化学研究的基础就是制备定向不同的单晶电极.本文建立了金属单晶电极制备方法,并报道了Cu2+在Pt单晶电极上UPD(欠电位沉积)过程的研究结果.

关键词: 单晶电极, 欠电位沉积, 循环伏安法

Abstract: A technique for preparing metal single crytal electrode is developed and the set-up associated to this technique has been also established.The results of underpotential deposition (UPD) of Cu2+ on Pt(100), Pt(111) and Pt(110) electrodes prepared by the present technique demonstrate that the use of single crystal electrodes can deepen the knowledge of electrochemical processes of surface at an atomic level.

Key words: Single crystal electrode, Underpotential deposition, Cyclic voltammetry
