Meso-alpo Prepared By Thermal Decomposition Of The Organic-inorganic Composite: A Ftir Study

Abstract

Mesporous ALPO was synthesised using cetyltrimethylammonium bromide (CTAB) as a structure-directing agent. FTIR spectroscopy was used to follow the formation of the ALPO mesophase by thermal decomposition of the aluminophosphate/surfactant composite and NH3 was used as probe molecule to monitor the surface acidity of the product.141417422Estermann, M., McCuster, L.B., Baerlocher, C., Merrouche, A., Kessler, H., (1991) Nature, 352, p. 320Davis, M.E., Saldarriaga, C., Montes, C., Garces, J., Crowder, C., (1998) Nature, 331, p. 698Kimura, T., Sugahara, Y., Kuroda, K., (1998) Micropor.
