This patent describes a composition consisting essentially of a layered clay homogeneously dispersed in an inorganic oxide matrix, such that the clay layers are completely surrounded by the inorganic oxide matrix, the inorganic oxide selected from the group consisting of alumina, titania, silica, zirconia, P{sub 2}O{sub 5} and mixtures thereof. This patent also describes a process of preparing a composition consisting essentially of a layered clay homogeneously dispersed in an inorganic oxide matrix, the process comprising mixing a clay with a hydrosol of a precursor of the inorganic oxide, forming spherical particles from the clay containing hydrosol and calcining the particles to form a composition comprising a clay homogeneously dispersed in an inorganic oxide matrix, such that the clay layers are completely surrounded by the inorganic oxide matrix.
