结论ESCA技术是直接鉴定电极表面生成物化学性质的一种有价值的辅助手段。很明显，许多关于电极反应的基本问题都可以很快得到解答。例如，图2a中的光谱最终显示了相氧化物而不是化学吸附的氧原子的存在，并且还指示了PdO 2的存在，这有力地支持了Hoare机制。我们认为，除了这些直接的分配，未来的研究，0 Is区使用各种ofelectrodes材料将允许表征过剩的氧物种，如OH~-，吸附水，和散装水合物。该方法对于鉴别电极表面的有机膜和无机膜也有一定的应用价值。这类结果显然对提出电化学机理有很大帮助。
CONCLUSIONSThe ESCA technique is a valuable aid in directly iden-tifying the chemical nature of species produced at elec-trode surfaces. It is clear that many fundamental ques-tions regarding electrode reactions can be quickly an-swered. For example, thespectrum in Figure 2a conclusively shows the presence of a phase oxiderather than chemisorbed oxygen atoms and also indicates the presence of Pd02, lending strong support to Hoare’s mechanism. We feel that, in addition to these direct assignments, fu-ture studies of the 0 Is region using a variety ofelectrode materials will allow characterization of excess oxygen species such as OH~, adsorbed water, and bulk hydrates. The approach should also be valuable in identification of organic and inorganic films which often foil electrode be-havior. Results of this kind can obviously be of great aid in proposing the electrochemical mechanism.
