Abstract

Le film mince de mnpo4,h2o est électrodéposé à partir d'une solution aqueuse contenant 0,2m de sulfate de manganèse; 5m d'acide phosphorique. L'électrodéposition a été effectuée par oxydation galvanostatique. La réaction d'électrodéposition se déroule en deux étapes l'oxydation électrochimique de mn(ii) en mn (iii) suivie d'une précipitation en milieu phosphorique (5m). L'influence des paramètres de synthèse sur la préparation du film mince de mnpo4, h2o est étudiée. La structure cristalline des dépôts étudiée par diffraction des rayons x a été correctement indexée à la structure monoclinique de mnpo4, h2o. L'étude morphologique est réalisée par microscopie électronique à balayage et révèle une surface poreuse. La taille des cristallites est calculée par l'équation de sherrer. Mots-clés : mnpo4, h2o; nanomatériau; couches minces ; électrodéposition anodique;diffraction des rayons x; microscopie électronique à balayage; spectroscopie infrarouge.
