金电极和纳米多孔金在离子液体中的电化学传感研究

摘要

金电极是电化学研究常用电极，本文以探究金电极在不同离子液体中的电化学行为为目的，利用循环伏安技术，研究了平面金电极和纳米多孔金电极在两种不同性质的离子液体中的氧化还原性质。结果表明金电极的微观结构和离子液体的性质是影响金电极电化学行为的重要因素。金电极的微观纳米化提高了电化学信号，降低了金的氧化电位；离子液体的活性使普通金电极表现出了良好的电催化能力。%Gold electrode is a common used electrode in electrochemical investigation.Aimed to explore the electrochemical behaviors of the gold electrode in different ionic liquids, the redox properties of the smooth gold electrode and nanoporous gold electrode in two ionic liquids were investigated via cyclic voltammetry.The results demonstrated that both the microstructure of the gold electrode and the properties of the ionic liquids affected the electrochemical behavior of the gold electrodes.The nanoporous structure increased the electrochemical signal and decreased the oxidative potential of gold, the unique property of the ionic liquid facilitated the electrocatalytic ability of the common gold electrode.
