'COMPOSITION INCLUDING A LANTHANUM PEROVSKITE ON AN ALUMINA OR ALUMINIUM OXYHYDROXIDE SUBSTRATE, PREPARATION METHOD AND USE IN CATALYSIS',

摘要

pA composition is described that 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, wherein after calcination at 700° C. 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 described composition can be used in the field of catalysis./p[US2012046163A1]
