METHOD FOR OBTAINING OXIDE CATALYSTS ON THE BASE OF EXFOLIATED LAYERED ALUMINOSILICATES

摘要

The present invention relates to the method of synthesising large-area oxide catalysts on the base of exfoliated layered aluminosilicates. As layered aluminosilicate are used bentonite, montmorillonite, nontronite and saponite.

1. The method for obtaining oxide catalysts on the base of exfoliated layered aluminosilicates, comprising: wherein the metal cations are introduced into the structure aluminosilicates such that at least one basic hydrophilic monomer is introduced to the interlayer space of layered aluminosilicate in the amount of 30% wt. to 90% wt. relative to the weight of aluminosilicate, or with the addition of a hydrophilic crosslinking monomer in the amount of up to 20 wt %. relative to the amount of remaining monomers, and in situ polymerization is carried out in aqueous solution, then the resulting hybrid inorganic-organic layer material is submitted to sorption of at least one metal cation from the aqueous solution of its salt, followed by thermal treatment in the temperature range of 400-700° C., in an oxidizing atmosphere.
