Patent ID: 8865120

Claim:
Process for the production of metal doped Zeolites or Zeotypes comprising the steps of: i) providing a dry intimate mixture of a Zeolite or Zeotype with one or more precursor compound or compounds comprising a complex formed out of a transition metal and a ligand, which has a structure of formula I: ML 1 m L 2 n (I) wherein: M is a metal selected from the group consisting of V, Cr, Mn, Fe, Co, Ni, Cu, Nb, Mo, Ru, Rh, Pd, Ag, and Ce; and L 1 is carbonyl, amine, alkyl, alkoxy, alkene, arene, phosphine or other neutral coordinating ligand; m is a number ranging from 0 to 6; n is a number equal to the valence of M; and L 2 is a diketonate, ketoiminato or related member of this homologous series like a ligand of formula II: wherein: R1 and R2 are independently alkyl, substituted alkyl, aryl, substituted aryl, acyl and substituted acyl; and ii) calcining the mixture without reduced pressure at a temperature and a time sufficient to mobilise and decompose the precursor compound; and iii) obtaining the metal-doped Zeolite or Zeotype.
