1 Highly uniform zeolite-supported metal complex catalysts
STRUCTURAL PARAMETERS estimated from crystallographic data. N is coordination number, R is interatomic distance; 2 is Debye-Waller factor. EXAFS data shown & IR data demonstrate presence of essentially molecular catalyst bonded to zeolite; structure is closely similar to that of precursor Ru(C2H4)2(acac)2. Family of such catalysts has been synthesized from acac complexes of Ru & of Rh on various zeolites. Changes in ligands on metal allow tuning of catalyst selectivity in ethylene conversion (dimerization vs. hydrogenation).
