In-situ Raman Spectroscopic Studies on Protonation of Polypyrrole Film Electrodes
Abstract
采用现场拉曼光谱结合循环伏安法研究在不同溶液中PH值对聚吡咯（PPy）膜电极的结构及氧化还原过程的显著影响，共振拉曼光谱结果证实了在较强酸性条件下PPy发生质子化。提出PPy质子化的可能形式，即加氢于吡咯环上的氮原子。 In-situ Raman spectroscopy combined with cyclic voltammetry has been applied toinvestigate strong eFFects of the Solution on the structure and redox process of polypyrrole(PPY)Film electrodes,The resonance Raman results conFirm that the protonation takes place in relativelystrong acidic solutions.A possible protonation Form of the PPY is proposed to conside the nitrogenatom of pyrrole ring as the protonating site.
