Patent

CA 2677958

The invention relates to a material in the form of a cellular solid monolith consisting of an inorganic oxide polymer. Said monolith comprises macropores which have an average size dA of 4 µm to 50 µm, mesopores that have an average size dE of 20 to 30 Å, and micropores which have an average size dI of 5 à 10 Å, said pores being interconnected. The inorganic oxide polymer has organic groups R of formula -(CH2)n-R1, wherein 0<=n<=5, and R1 is selected from among a thiol group, a pyrrole group, an amino group having one or more optional, optionally substituted alkyl, alkylamino, or aryl substituents, an alkyl group, or a phenyl group optionally having an alkyl-type substituent R2. The disclosed material can be used as a substrate for a metal catalyst and for decontaminating liquid or gaseous media.

L'invention concerne un matériau sous forme d'un monolithe solide alvéolaire constitué par un polymère d'un oxyde inorganique. Le monolithe comprend des macropores ayant une dimension moyenne dA de 4 µm à 50 µm, des mésopores ayant une dimension moyenne d.SIGMA. de 20 à 30 Å et des micropores ayant une dimension moyenne di de 5 à 10 Å, lesdits pores étant interconnectés. Le polymère d'oxyde inorganique porte des groupements organiques R répondant à la formule -(CH2)n-R1 dans laquelle 0<=n<=5, et R1 est choisi parmi un groupe thiol, un groupe pyrrole, un groupe amino qui porte éventuellement un ou plusieurs substituants alkyle, alkylamino ou aryle éventuellement substitué, un groupe alkyle, ou un groupe phényle qui porte éventuellement un substituant R2 de type alkyle. Le matériau est utile comme support de catalyseur métallique, et pour la décontamination de milieux liquides ou gazeux.
