Patent

CA 2297651

The invention relates to a method for producing a catalyst containing one or several metals from the group of metals comprising the sub-groups Ib and VIIIb of the periodic table on porous support particles, characterised by a first step in which one or several precursors from the group of compounds of metals from sub-groups Ib and VIIIb of the periodic table is or are applied to a porous support, and a second step in which the porous, preferably nanoporous support to which at least one precursor has been applied is treated with at least one reduction agent, to obtain the metal nanoparticles produced in situ in the pores of said support.

L'invention concerne un procédé de production d'un catalyseur présentant un métal ou plusieurs métaux du groupe des métaux comprenant les sous-groupes Ib et VIIIb de la classification périodique des éléments, sur des particules de support poreuses. Ce procédé se caractérise en ce que: dans une première étape, on applique sur un support poreux un ou plusieurs précurseurs du groupe des composés comprenant les composés des métaux des sous-groupes Ib et VIIIb de la classification périodique des éléments; et, dans une seconde étape, on traite le support poreux, de préférence nanoporeux, sur lequel est appliqué au moins un précurseur, avec au moins un agent de réduction, ce qui permet d'obtenir des nanoparticules qui sont produites in situ dans les pores du support.
