MATIERES POREUSES SYNTHETIQUES A PAROIS MICROPOREUSES DEFINISSANT DES MESOPORES D'ETROITE DISTRIBUTION DE TAILLE

摘要

A process for preparing an inorganic porous material, includes the steps of forming a solution of a hydrolyzable inorganic compound with a non-ionic surfactant having organic molecules; inducing growth and condensation of a solid composition comprising an inorganic composition in intimate contact with said organic molecules; and extracting said organic molecules from said inorganic composition so as to provide said inorganic porous material having wall portions defining mesopore-sized channels having a mean diameter of between about 15 ANGSTROM to about 100 ANGSTROM and a narrow diameter distribution of less than or equal to about 30 ANGSTROM , said material having a void volume from said mesopore-sized channels of at least about 0.1 cc/g.
