【摘要】 <正>将固体微粒固定在电极表面是研究三相体系电化学反应的有效方法[1]。本工作将不溶于水的硫靛(thioindigo)粉末打磨到固体碳糊表面制成TI/CPE电极,用于其还原过程的固态(光谱)电化学测量。图1所示的CV显示了一对还原/再氧化峰C/A,首圈的还原峰C极小,而在负于该峰约500m V处出现一很高的还原峰
【Abstract】 Immobilizing particles on electrodes is a powerful technique for studying the electrochemistry of three-phase systems. Large "break-in" overpotential was observed in the initial stage of the reduction of thioindigo microparticles attached to the surface of a solid carbon paste electrode(TI/CPE), but not when the particles were mixed with the carbon paste. This additional overpotential correlates with the Na+ ions that entered crystal lattices of the particles across the electrolyte/particle interface.
