Abstract
The invention relates to a partially crystalline mesostructured material which consists essentially of a compound chosen from cerium oxide, zirconium oxide, titanium oxide or a mixture of these compounds, and which is characterized in that it comprises at least one element M in solid solution in said oxide. This material is obtained by means of a process in which (a) a partially crystalline mesostructured starting material is brought into contact with a solution of the element M which has a concentration of this element of at most 2 mol/l; and then (b) the material obtained after this process of bringing into contact with said solution is calcinated at a temperature of at most 500.degree. C.; steps (a) and (b) being repeated, where appropriate, until a material having the desired content of element M is obtained. The material can be used as a catalyst.
