Zusammenfassung
We report the synthesis and characterization of a mesoporous zirconium oxophosphate with a cubic Ia (3) over bard symmetry. The ordered porous material was obtained by supramolecular self-assembly of a specific cationic surfactant combined with zirconium sulfate as inorganic precursor. A systematic investigation of the effects of initial reagent ratios and synthesis procedures is reported. Both the as-prepared and the template-free cubic porous zirconium oxophosphate materials were characterized by X-ray diffraction and transmission electron microscopy. The template-free material was additionally characterized by N-2 sorption. The removal of the template was studied by thermogravimetry/differential thermal analysis coupled with mass spectrometry and in situ high- temperature XRD. In addition, pyridine sorption-FTIR experiments were performed to evaluate the Lewis and Bronsted acidity.
