Abstract
Various metal-substituted ammonium gallophosphates (metal is Zn, Mn, Mg, and Fe) have been synthesized. Characterization by X-ray diffraction (XRD), X-ray absorption spectroscopy (XAS), and P-31 MAS and Ga-71 MAS NMR shows that the structures are similar and isostructural to:the known ammonium cobalt gallophosphate hydrate, [NH4][CoGa2P3O12(H2O)(2)]. It is concluded from a combined in situ XRD/XAS study that the gallophosphate molecular sieves described here are not thermally stable and lose their microporous nature above 350 degrees C
