Surface Structure and Anion Effects on Electrooxidation of Isopropanol on Pt(<i>hkl</i>).

ABSTRACT: This study focuses on the electro-oxidation of isopropanol on low-index platinum single-crystal surfaces─Pt(111), Pt(110), and Pt(100)─in acidic electrolytes containing either sulfuric acid (H₂SO₄) or perchloric acid (HClO₄). The aim is to elucidate the roles of crystallographic orientation and electrolyte anions in the reaction pathway and associated dynamic instabilities. While conventional voltammetric and spectroscopic techniques provide insights into reaction products and adsorbed intermediates, galvanostatic experiments are employed here to probe the emergence of potential oscillations, which serve as sensitive indicators of nonsteady-state surface processes. The results reveal a marked dependence of oscillatory behavior on both the electrode surface
