Abstract
The invention relates to an ordered mesoporous or mesostructured compound comprising a mineral phase of aluminium in which at least partially crystalline particles of a cerium, titanium or zirconium compound are dispersed. The inventive compound is characterised in that the chemical consistency thereof is such that the heterogeneity domains are at most 100 nm.sup.2 The invention also relates to the aforementioned ordered mesoporous or mesostructured compound which comprises at least one element M in solid solution in said particles. Moreover, the invention relates to the methods of preparing said ordered mesoporous or mesostructured compounds. The inventive materials can be used, for example, in the field of catalysis.
