Cu UPD at Pt(100) and stepped faces Pt(610), Pt(410) of platinum single crystal electrodes

详细

The processes of adsorption/desorption of copper adatoms on the basal Pt(100) face and stepped Pt(610), Pt(410) surfaces have been studied in perchloric acid solution by cyclic voltammetry. It has been shown that the positions of the Cu stripping peaks are determined by perfection of the adlayer. The “island” model is suggested to describe electrochemical behavior of the Pt(hkl)+Cu_ad system. Obtained results are important for target modification of shape-controlled nanoparticles that are used in electrocatalysis.
