Title (EN) PROCESS FOR SYNTHESISING POROUS INORGANIC MATERIALS
(FR) PROCEDE DESTINE A SYNTHETISER DES MATERIAUX INORGANIQUES POREUX
Abstract:
(EN) The invention pertains to a process for synthesising a porous inorganic material having an MoPD of 0.8-2.0 nm, characterised in that the synthesis is performed in the presence of templates containing one or more amphipolar compounds having at least two cationic or anionic head groups and a hydrophobic part. Preferably, at least a portion of the head groups of the amphipolar compound has a cationic nature. The process according to the invention makes it possible to synthesise novel porous mixed oxides, in particular metallosilicates, more in particular aluminosilicates, with an MoPD of 0.8-2.0 nm. These materials are especially attractive for use in catalysis.
(FR) L'invention porte sur un procédé destiné à synthétiser un matériau inorganique poreux possédant un diamètre de pores (MoPD) de l'ordre de 0,8 à 2,0 nm, ce procédé étant caractérisé en ce que l'on effectue la synthèse en présence d'agents structurants contenant un ou plusieurs composés amphipolaires possédant au moins deux groupes de tête cationiques ou anioniques ainsi qu'une partie hydrophobe. De préférence, au moins une portion des groupes de tête du composé amphipolaire possède une nature cationique. Le procédé selon l'invention permet de synthétiser de nouveaux oxydes mixtes poreux, notamment des métallosilicates, et plus particulièrement des aluminosilicates, présentant un diamètre de pores de l'ordre de 0,8 à 2,0 nm. Ces matériaux présentent un intérêt particulier pour la catalyse.
