Sobre IBD

L’objectif de ce travail est la conception et l’étude de jonctions à base de matériaux semiconducteurs α-Fe2O3 et TiO2 poreux par des méthodes électrochimiques. Dans un premier temps, l’élaboration de TiO2 poreux a été réalisée à l’aide d’un polymère comme agent structurant, et l’influence de ce dernier sur les films minces de TiO2 a été analysée. Cette étape a été accompagnée par des études structurales, morphologiques et optiques afin de déterminer les conditions optimales pour obtenir des couches poreuses. Dans un second temps, la formation des couches d’α-Fe2O3 a été optimisée par électrodéposition. Enfin, l’efficacité des matériaux et des jonctions formées a été évaluée à travers l’étude de la dégradation d’un colorant modèle, le bleu de méthylène, en fonction de la nature du photocatalyseur utilisé.
