CA 2434769
The invention concerns a heat-stable mesostructured material, for use as heterogeneous catalyst, wherein the mesostructured walls comprise: (a) a mineral matrix; and (b) dispersed within said mineral matrix (a), particles of nanometric dimensions based on at least a rare earth T and on at least a transition element M different from said rare earth. The invention also concerns a method for obtaining such a material.
La présente invention concerne un matériau mésostructuré, thermiquement stable, utile à titre de catalyseur hétérogène, dans lequel les parois de la mésostructure comprennent: (a) une matrice minérale; et (b) dispersées au sein de cette matrice minérale (a), des particules de dimensions nanométriques à base d'au moins une terre rare T et d'au moins un élément de transition M différent de cette terre rare. L'invention concerne également un procédé d'obtention d'un tel matériau.
