In the crystal lattice incorporating nanometer crystalline particles containing a solid solution-like metal mesostructured material
The present invention, cerium, zirconium, nanoscale particles of a metal oxide selected from oxides of rare earth metals other than titanium or cerium, which are dispersed in the inorganic layer, preferably relates to the thermal stability of the mesostructured material . The oxides containing at least one metal element M of the solid solution like cationic form in the crystalline structure of the oxide. The present invention is further such materials also relates to a particular method of manufacturing a material in the form or carrier for the catalyst species of heterogeneous catalysts.
