Abstract

A lamellar mesostructured hexadecyltrimethylammonium (C16TMA)-aluminophosphate material was hydrothermally prepared from the mixture of Al(OiC3H7)3, 85%H3PO4, C16TMACl, (CH3)4NOH, CH3OH, and H2O. The XRD pattern of the as-synthesized product indicated that the product had a layered structure, and the SEM and TEM images also supported this result. The27 Al MAS NMR spectrum of the product showed the presence of 4-coordinated Al composed of Al(OP)4, and the 31P MAS NMR spectra showed the presence of 4-coordinated P composed of O-P(OAl)3, including HO-P(OAl)3. Judging from the composition of the product measured by chemical analysis (1.4C16TMA·Al3P4O16·xH2O), 4-coordinated P atoms were composed of HO-P(OAl)3 and C16TMAO-P(OAl)3.
