The composition according to the invention includes a perovskite of the formula LaMO3, where M is at least one element selected from among iron, aluminium or manganese, in the form of particles dispersed on an alumina or aluminium oxyhydroxide substrate, characterised in that after calcination at 700ºC for 4 hours, the perovskite is in the form of a pure crystallographic phase, and in that the size of the perovskite particles does not exceed 15 nm. The composition according to the invention can be used in the field of catalysis.
La composition de l'invention comprend une pérovskite de formule LaMO3 dans laquelle M représente au moins un élément choisi parmi le fer, l'aluminium ou le manganèse, sous forme de particules dispersées sur un support d'alumine ou d'oxyhydroxyde d'aluminium, caractérisée en ce qu'après calcination à 700°C, 4 heures, la pérovskite se présente sous la forme d'une phase cristallographique pure et en ce que les particules de pérovskite présentent une taille est d'au plus 15 nm. La composition de l'invention peut être utilisée dans le domaine de la catalyse.
