Development of Simultaneous Observation for Electronic Structures of Surface Coadsorption Layers and Application to Electrode Reaction

金属表面上的共吸附层是催化和电极反应的模型。为了揭示表面共吸附层的电子结构，有必要创建共吸附层的混合比系统地改变。在这项研究中，我们创建了不同的混合比共吸附层，通过使用激光诱导热脱附方法，并测量了不同的共吸附层的电子结构，同时通过位置敏感的电子能量分析仪。结果表明，X射线吸收谱和共振俄歇电子能谱可用于表面共吸附层的电子结构测量。

Coadsorption layers on a metal surface are models of catalytic and electrode reactions. In order to reveal the electronic structures of the surface coadsorption layers, it is necessary to create the coadsorption layers whose mixing ratios are systematically changed. In this study, we created the different mixing ratio coadsorption layers by using a laser induced thermal desorption method, and measured the electronic structures of the different coadsorption layers simultaneously by a position-sensitive electron energy analyzer. As a result, the X-ray absorption spectroscopy and resonant Auger electron spectroscopy is able to apply for the electronic structure measurements of surface coadsorption layers.
