MESOSTRUCTURED ORGANIC/INORGANIC HYBRID MATERIAL

摘要

An organic/inorganic hybrid material (OIHM) that consists of elementary spherical particles is described, whereby each of said spherical particles consists of a mesostructured matrix that is based on silicon oxide and organic groups with reactive terminal groups that are linked covalently to the inorganic structure, whereby said mesostructured matrix has a pore size of between 1.5 and 30 nm and has amorphous walls with a thickness of between 1 and 20 nm. Said elementary spherical particles have a maximum diameter of 10 mum. The matrix that is based on silicon oxide can contain aluminum, titanium, zirconium and cerium. Two methods for preparation of said material are also described.
