Abstract
A method for preparing a composition includes silico/germano-metal particles functionalized by at least one organic group, which involves:—carrying out a hydrothermal treatment of a hydrogel precursor of the silico/germano-metal mineral particles, and—preparing a hydrogel including silico/germano-metal particles having at least one organic group by co-precipitation in an aqueous medium. A composition including functionalized silico/germano-metal mineral particles of which 1% to 75% of the silicon atoms and/or of the germanium atoms are covalently bonded to at least one organic group is also described.
