The invention is directed to a catalytic principle based on zeolite crystallites attached to support or incorporated in a matrix and a catalytically active principle incorporated in the zeolite, the said crystallites having a diameter of between 20 and 300 nm and said catalytically active principle having a formula corresponding to: CoMn2(O)(R-COO)6 L1k1 L2k2 wherein: R is an optionally substituted C1-C4 alkyl; L1 is an optionally substituted nitrogen containing carboxylic acid or salts thereof; L2 is selected from the group consisting of H2O, an optionally substituted C1-C4 alkyl containing carboxylic acid, an optionally substituted C5-C6 cycloalkyl or heterocycle, an optionally substituted C5-C6 heteroaryl or aryl; and k1 + k2 = 3; wherein the zeolite has an Si/Al atomic ratio of at least 8, as well as to a method for the oxidation of alkyl aromatics compounds employing the catalytic principle
L'invention concerne un principe catalytique basé sur des cristallites de zéolite attachés à un support ou incorporés dans une matrice et un principe actif du point de vue catalytique incorporé dans la zéolite, lesdits cristallites ayant un diamètre compris entre 20 et 300 nm et ledit principe actif du point de vue catalytique ayant une formule correspondant à : CoMn2(O)(R-COO)6 L1 k1L2 k2 où : R est un alkyle en C1-C4 facultativement substitué ; L1 est un acide carboxylique contenant de l'azote facultativement substitué ou des sels de celui-ci ; L2 est sélectionné dans le groupe constitué de H2O, d'un acide carboxylique contenant un alkyle en C1-C4 facultativement substitué, d'un cycloalkyle ou hétérocycle en C5-C6 facultativement substitué, d'un hétéroaryle ou aryle en C5-C6 facultativement substitué ; et k1 + k2 = 3, la zéolite ayant une proportion atomique Si/Al d'au moins 8 ; ainsi qu'un procédé pour l'oxydation de composés d'aromatiques alkyliques employant le principe catalytique.
