EXAFS study of nickel exchanged into zeolite Y.
In: Journal de Physique, Colloque C8, Suppl. 12, Vol. 47: pp. 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
