摘要：

Studies are reported in which surface layers formed by immersion of a well-defined Pt(111) electrode surface into aqueous CaBr//2 solutions were characterized with regard to structure, composition, and reactivity by means of low-energy electron diffraction (LEED), Auger electron spectroscopy, and linear-scan voltammetry. Voltammetry revealed a series of potential-dependent adsorption processes. Comparison of voltammetric curves with surface analysis data (Auger) and structural data (LEED) permitted identification of adsorbed layer structural transitions and adsorption/desorption processes responsible for the electrochemical behavior.
