Abstract
Material with hierarchical porosity consisting of at least two elementary spherical particles, each one of said particles comprising a matrix based on silicon oxide, mesostructured, having a mesopore diameter ranging between 1.5 and 30 nm and exhibiting amorphous and microporous walls of thickness ranging between 1.5 and 50 nm, said elementary spherical particles having a maximum diameter of 200 microns. The matrix based on silicon oxide can contain aluminium. The preparation of said material is also described.
