Woolery, G.; Kuehl, G.; Chester, A.; Bein, Thomas; Stucky, Galen D.; Sayers, D. E. (1986): EXAFS study of nickel exchanged into zeolite Y. In: Journal de Physique, Colloque C8, Suppl. 12, Vol. 47: S. 281-284




EXAFS and near edge spectroscopy were used to monitor changes i n Ni coordination as a function of treatment conditions after aqueous exchange into zeolite Y. Our results suggest that after calcination and dehydration under the conditions of this study, major site occupancy for Ni appears to be in the tri-coordinate exchange sites , and not i n the hexagonal prisms as suggested by previous x-ray diffraction results.
