ABSTRACT:
A material with a hierarchical porosity is described, constituted by at least two spherical elementary particles, each of said spherical particles comprising zeolitic nanocrystals having a pore size in the range 0.2 to 2 nm and a matrix based on silicon oxide, which is mesostructured, having a pore size in the range 1.5 to 30 nm and having amorphous walls with a thickness in the range 1 to 20 nm, said spherical elementary particles having a maximum diameter of 10 μm. the matrix based on silicon oxide may contain aluminium. The preparation of said material is also described.
