Abstract
Material with hierarchical and organized porosity in the microporosity and mesoporosity domains, 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 microporous and crystallized walls of thickness ranging between 1 and 60 nm, said elementary spherical particles having a maximum diameter of 200 microns. The preparation of said material is also described.
