| 摘 要： | 报道了普鲁士蓝(PB)膜修饰Pt电极在CdCl_2溶液中进行循环伏安(CV)扫描,衍生为含有部分六氰亚铁酸镉(CdHCF)混合修饰膜的电化学反应,并对其反应机理进行了电化学和现场红外光谱电化学(FTIRs)的研究.实验结果表明,这一混合膜中PB和CdHCF两种成分之间的相互影响并不大,两种物质基本上保持了各自为纯物质时的电化学特性.

| Abstract: | Plussian blue(PB)/Pt modified electrode was studied in the CdCl-, electrolyte solution by cyclic voltammetry and in situ FFIR spectroelectrochernistry. It was found that Cadmium ion was capable of substituting the high-spin iron of PB in an electrochemically induced substitution reaction and hexacyanoferrate cadmium (CdHCF) can be formed in the PB film. But PB and CdHCF in mixture film showed their own electrochemistry properties without serious effect on each other. The mechanism of substitution reaction has been given in detail. |
