摘要：

Two aspects of the adsorption properties of Pt single-crystal electrodes are examined. On the one hand, the adsorption of urea molecules on Pt(100) electrodes is studied by means of charge displacement experiments and in-situ FTIR spectroscopy. A comparison is made with the homologous Rh(100) surface. On the other hand, the possible contribution of anions to the redox process undergone by As and Pi irreversibly adsorbed on Pt(lll) is also investigated. (C) 1998 Elsevier Science B.V.
