NOUS AVONS ETUDIE CERTAINS PHENOMENES D'ADSORPTION ELECTROCHIMIQUE (ELECTROSORPTIONS) A L'INTERFACE PT(111)/ELECTROLYTE ACIDE ET L'INFLUENCE DES ANIONS DE LA SOLUTION, D'UNE PART EN SPECTROSCOPIE D'IMPEDANCE D'AUTRE PART EN ABSORPTION X A L'AIDE DU RAYONNEMENT SYNCHROTRON. L'ELECTROSORPTION D'HYDROGENE SUR CETTE SURFACE EST UN PHENOMENE RAPIDE QUI NECESSITE DES MESURES D'IMPEDANCE ELECTROCHIMIQUE JUSQU'AU MEGAHERTZ ET A DONC IMPOSE LA MISE AU POINT D'UN MONTAGE PARTICULIER. A PARTIR DE CES MESURES, IL A ETE POSSIBLE DE DETERMINER CERTAINS PARAMETRES CINETIQUES ET THERMODYNAMIQUES DES REACTIONS INTERVENANT A L'INTERFACE ELECTROCHIMIQUE. EN PARTICULIER, POUR L'ETAT HABITUEL, NOUS AVONS PU DETERMINER LES CINETIQUES ASSOCIEES A L'ELECTROSORPTIO...
