Abstract
Adsorption and oxidation processes of cyanate (OCNâ) were studied on polycrystalline platinum and Pt(1Â 0Â 0), Pt(1Â 1Â 0) and Pt(1Â 1Â 1) surfaces in alkaline solution (pH 9). On Pt(poly), Pt(1Â 0Â 0) and Pt(1Â 1Â 0), it has been found that cyanate chemisorbs dissociatively, with production of adsorbed CO. Oxidation of cyanate thus follows a pathway involving COad on polycrystalline Pt and these single crystal faces. COad has not been observed during oxidation of cyanate on Pt(1Â 1Â 1); thus another pathway, involving direct oxidation of OCNâ, has been identified for cyanate oxidation on platinum surfaces.
