The adsorbate formed by adsorption of thiophenol on a polycrystalline gold electrode and brought into contact with aqueous solutions of 1 M HClO4 and 0.1 M KClO4 has been studied using cyclic voltammetry and surface-enhanced Raman spectroscopy. A strong adsorption is deduced from observations made using cyclic voltammetry. From the SER spectra, interactions of thiophenol with the gold surface via a gold-sulfur bond with the aromatic ring pointing away from the surface is concluded for both electrolyte solutions.
采用循环伏安法和表面增强拉曼光谱法研究了吸附在多晶金电极上的巯基苯酚在 1 M HClO4 和 0.1 M KClO4 水溶液中形成的吸附物。从循环伏安法的观察结果推断出强吸附作用。从 SER 光谱可以得出，对于这两种电解液，噻吩酚通过金-硫键与金表面相互作用，芳环指向远离表面的方向。
