Abstract
Il est possible d'obtenir un matériau en silice mésoporeux en condensant un acide polysilicique à partir d'une solution en présence d'un tensio-actif tel qu'une akylamine à chaîne longue. Ces matériaux mésoporeux ont une grosseur de pores importante qui leur permet d'être utilisés en filtration comme support de catalyseur, et dans des procédures de séparation dans lesquelles les zéolites classiques ont une grosseur de pores trop petite.
