Jl. Bonardet et al., MICROPOROSITY IN HETEROPOLYOXOMETALATES - A XE-129 NMR-STUDY, Colloids and surfaces. A, Physicochemical and engineering aspects, 72, 1993, pp. 191-195
Moffat has shown (J.B. Moffat, J. Mol. Catal., 52 (1989) 169) that cer
tain of the monovalent salts of heteropolyoxometalates may be prepared
with microporous structures. The Xe-129 NMR method confirms the exist
ence of this microporosity and shows that it is homogeneous and organi
sed and can be compared to the porous system of zeolites.
