LaFeO3 thin films as relevant models for the surface investigation of 3-way catalysts

Pardis Simon

Résumé

Lanthanum orthoferrite, a highly potential three-way catalyst, shaped as apolycrys-talline thin film has been comprehensively analysed by combining bulk and surface characterization techniques. The possibility to accomplish unprecedented surface information has been presented, thanks to the combined use of LEIS, XPS and ToF-SIMS. The structural, morphological and surface properties at nano-metric scale make such thin films indistinguishable from powdered solids. Thus, 5 the relevance of using such model materials for advanced surface investigations of LaFeO 3±δ-based three-way catalysts has been demonstrated.
