ABSTRACT:
The invention concerns a method for preparing organic-inorganic hybrid materials with controlled porosity and functionality comprising hydrolysis and condensation polymerization of a compound of formula (I): Z-R1—Si(OR)(OR′)(OR″), with an alkaline or alkaline-earth silicate in a mol ratio of (I)/(silicate)=1:9, in the presence of a non-ionic surfactant, to form a mesoporous silica represented by Z-R1—SiO1.59 SiO2, whereon is then anchored an organic compound, represented by (Δ)N—H, comprising a —NH— group capable of reacting with Z, to form a functionalized mesoporous silica represented by (Δ)N—R—SiO1.59 SiO2,which is optionally complexed with a metallic cation to form an organometallic complex. The invention also concerns the use of these materials to separate gases.
