HYDROTHERMAL SYNTHESIS OF CERIUM ALUMINOPHOSPHNTE

Cerium(III) aluminophosphate molecular sieve has been synthesized star ting from aluminum hydroxide, phosphoric acid, hydrated cerium chlorid e and water, in the presence of a di-isopropylamine organic template, This material has a tetrahedral framework of aluminum (AlO2)(-) and ph osphorus (PO2)(+). The obtained structure was similar to that of ALPO- 11. The materials have been characterized by using various physicochem ical methods. The incorporation of Ce(III) ions into the aluminophosph ate matrix did not change the ALPO-11 structure, but did, however, inc rease the surface area and total acidity.
