Abstract
A permanent modification of Pt and Au electrode surfaces was observed after the oxidation of pure neutral or acidic ethylenediamine (EDA). P latinum and gold were coated by an organic compound strongly tied thro ugh oxygen atoms to metal atoms. The presence of water is of importanc e: the larger the water concentration the less stable the coating. Thi s phenomenon was studied by coupling electrochemistry, in situ EQCM an d ex situ XPS chemical analysis for Pt. (C) 1997 Elsevier Science S.A.
