Abstract
The work presents the preparation and characterization of Fe and Co complexes with 2,2’bipyridine (2,2’-bpy) ligands supported on Y zeolite as well as their catalytic activity for ethylene dimerisation. The catalysts were characterized by using XRD, FTIR, DR-UV-Vis spectroscopy and TG-DTA analysis. It was found that Co(2,2’-bpy)2Cl2 supported on Y zeolite has an exceptional good selectivity (>95%) to the formation of 1-butene.
