我们同时采用伏安法和表面等离子体共振（SPR）测量并监测金电极上的电化学过程。 SPR不仅对金电极上的吸附层敏感，而且对溶液相的介电性能也敏感。因此，电化学调制的扩散层可以通过SPR来检测。我们测试了两个电化学过程的时间微分SPR数据与电极电流之间的关系，并证实了使用电化学SPR测量的可能性。
We simultaneously employed voltammetry and surface plasmon resonance (SPR) measurements and monitored electrochemical processes on gold electrode. SPR is sensitive not only to the adsorbed layer on the gold electrode, but also to the dielectric properties of the solution phase. Therefore, an electrochemically modulated diffusion layer can be detected by SPR. We tested the relationship between the time differential SPR data and the electrode current for two electrochemical processes and confirmed the possibility of using electrochemical SPR measurement.
