Abstract:
1. A process for preparing metal-containing crystalline silicates, wherein a metal is introduced into a gallo-silicate, gallo-titanium silicate, boro-silicate or boro-titanium silicate and the gallo-silicate, gallo-titanium silicate, boro-silicate or boro-titanium silicate is then calcined at temperatures above 600° C., wherein gallium or boron is removed from the crystal lattice, wherein the silicate has a zeolite structure, the topology is selected from the group consisting of AEL, BEA, CHA, EUU, FAU, FER, KFI, LTA, LTL, MAZ, MOR, MEL, MTW, LEV, OFF, TON and MFI and the metal is a noble metal or transition metal, wherein the metal is introduced into the gallo-, gallo-titanium-, boro- or boro-titanium silicate via an aqueous ion exchange, aqueous impregnation, incipient wetness method or solid-state exchange.
