摘要
利用循环伏安法在两种不同组成的电解液中进行铂电极上普鲁士蓝膜的电化学沉积,在氯化钾溶液中测量了修饰膜的循环伏安行为,比较了两种膜的电化学阻抗谱。修饰普鲁士蓝膜铂电极的电化学阻抗谱测量结果表明,沉积条件及其沉积膜厚度均对电子传递过程产生影响。
Two kinds of electrochemically deposited Prussian blue film(PB)modified platinum electrode were studied by cyclic voltammetry and electrochemical impedance spectra(EIS).The electrodeposition and redox processes of the PB in two type solutions,i.e. absence or presence of Phenanthroline,were discussed with the observed CV plots.The measured impedance spectra were also analyzed.Experimental results show that the electron transfer process was influenced by the conditions of deposition and varied PB films thickness.
