Multimetalite catalysts
Abstract
Abstract A NEW CLASS OF INORGANIC COMPOUNDS HAS BEEN PREPARED IN WHICH THE CATION IS A TRANSITION METAL COMPLEX AND THE ANION IS A HETERPOLY ION. THESE COMPOUNDS CAN BE REPRESENTED BY THE GENERAL EMPIRICAL FORMULA: (MLN)M/N(M''XM"YOZ) WHERE M= A TRANSITION METAL OR A MIXTURE OF A TRANSITION METAL WITH HYDROGEN N= THE NUMBER OF LIGANDS LN= A SET OF N LIGANDS AT LEAST ONE OF WHICH FUNCTIONS AS A REDUCING AGENT M= THE CHARGE ON THE ANION N= THE CHARGE ON THE CATION M''= A TRANSITION METAL OR NON-METAL OR HYDROGEN M"= A METAL SELECTED FROM THE GROUP CONSISTING OF GROUP V-B AND VI-B METALS X IS 1 OR 2 Y IS BETWEEN 5 AND 20 Z IS BETWEEN 20 AND 50 THERMAL DECOMPOSITION OF THE ABOVE COMPOUNDS IN AN INERT ATMOSPHERE RESULTS IN A NEW SERIES OF MATERIALS REFERRED TO HEREIN AS "MULTIMETALITIES" WHICH HAVE BEEN FOUND TO POSSESS UNUSUAL CATALYTIC PROPERTIES.
