The direct observation of cation hydrolysis in lanthanum zeolite-Y by neutron diffraction

Abstract

Neutron diffraction studies on a partially dehydrated sample of lanthanum zeolite-Y (Si/Al = 2.61) reveal the locations of the hydrogen atoms, thus providing direct evidence for the cation hydrolysis and Brønsted acidity that account, tn part, for the catalytic activity of this faujasite zeolite.
