METAL DOPED ZEOLITE AND METHOD FOR PRODUCTION THEREOF

摘要

The invention relates to a metal doped or metal exchanged zeolite, wherein the doping metal is present in the zeolite in the isolated form of individual atoms i.e. as a monomeric and/or dimeric species. The invention further relates to a method for production of such a metal exchanged zeolite. Said metal doped zeolites are useful, in particular, for the reduction of nitrogen oxides.
