Estimating the term…
The invention relates to a mesostructural material, preferably thermally stable, comprising a mineral phase within which nano-scale particles of a metallic oxide are dispersed, selected from a cerium, zirconium, titanium or rare earth metal oxide other than that of cerium. Said oxide comprises at least one metallic element M in a cationic form in a solid solution within the crystalline structure of said oxide. The invention further relates to a method for production of such a material, particularly in the form of heterogeneous catalysts or as a support for catalytic species.
A mesostructured material comprising a mineral phase within which are dispersed particles of nanometric dimensions comprising at least one metal oxide in the crystalline state selected from a cerium oxide, a zirconium oxide, a titanium oxide and an oxide of a rare earth other than cerium, said oxide comprising at least one metallic element M in the cationic form, in solid solution within the crystalline lattice of said oxide.
A material comprising particles of cerium oxide integrating manganese in solid solution within the walls of its mesostructure, as a catalyst for absorption of oxides of nitrogen.
