本文综述了SO_（42）~-、Cl ~-、Br ~-和I ~-在Au（111）电极表面吸附的热力学、光谱和X射线衍射研究。热力学实验提供了有关的表面浓度的具体吸附的阴离子，吉布斯吸附能和每一个吸附的阴离子的单位电荷流到界面的数量。二次谐波产生和表面X射线散射揭示了离子吸附对界面的电子和晶体结构的影响。从这些微观研究中获得的原子信息用于讨论热力学数据并验证界面的理论模型。它已被证明，在金属电极上的离子吸附的完整描述需要协调使用的宏观和微观技术。(C)1998由Elsevier Science Ltd.出版。保留所有权利。
This paper reviews thermodynamic, spectroscopic and X-ray diffraction studies of SO42-, Cl-, Br- and I- adsorption at the Au(111) electrode surface. The thermodynamic experiments provided information about surface concentrations of specifically adsorbed anions, Gibbs energies of adsorption and the numbers of unit charge flowing to the interface per one adsorbed anion. Second harmonic generation and surface X-ray scattering revealed the affect of ionic adsorption on the electronic and crystallographic structure of the interface. The atomistic information derived from these microscopic studies was used to discuss the thermodynamic data and to verify the theoretical models of the interface. It has been shown that complete description of ionic adsorption at metal electrodes requires a concerted use of the macroscopic and microscopic techniques. (C) 1998 Published by Elsevier Science Ltd.
