Abstract:
The structure of the bulk proton sites in dehydrated solid Keggin-type heteropoly acids (HPA) H3PW12O40 and H4SiW12O40 was determined by 17O NMR. The terminal W=O oxygen atoms in Keggin heteropolyanions were found to be the predominant protonation sites. The protonation of HP As in solution is also discussed on the basis of 17O NMR data.
