A neutron diffraction study of acid sites in H-SAPO-37
Abstract
A powder neutron diffraction study of H-SAPO-37 (Fd3; a= 24.804(2)Å; Rp= 2.98%, Rwp= 3.73%, χ2= 1.966) reveals AI/P alternation in the framework, with Si substituting for P; protonation, in order of decreasing occupancy, is observed at O(1), O(2) and O(3).
