Abstract

A detailed study of the voltammetry curves of Pt (111) prepared by the flame method has provided strong evidence that the anomalous features reported originally by Clavilier et al., are associated with the specific adsorption of anions rather than hydrogen adsorption. In the case of HClO₄ or HF electrolytes such features are attributed to the adsorption of hydroxy ions (incipient oxidation) whereas in H₂SO₄ they are caused by the adsorption of sulfate or bisulfate ions.
