本文介绍了测量0.05M吡啶+0.1MKCl水溶液中,,吡啶吸附在光滑和粗糙化Ag电极上的导纳频谱。根据非法拉第吸附的新宏观模型,对该导纳频谱进行分析,求出各不同电位下,吡啶在Ag电极上吸附阻抗的等效电路中各元件及参数的值。并将它们对电位的依赖性与这个体系表面喇曼散射的电位依赖性进行比较,发现有一些相关之处。
This article describes the measurement of admittance spectra of pyridine adsorbed on smooth and roughened Ag electrodes in 0.05M pyridine + 0.1M KCl aqueous solution. According to the new macroscopic model of Faraday adsorption, the admittance spectra were analyzed and the values of the components and parameters in the equivalent circuit of pyridine adsorbed on the Ag electrode under different potentials were obtained. And compared their dependence on potential with the potential dependence of Raman scattering on the surface of this system and found some correlations.
