dc.description.abstract Metal containing aluminophosphate molecular sieves MeAPOs (Me: Fe, Sn, Co) are synthesized in AEL and AFI structure types by stat ic hydrothermal crystal l izat ion. These materials are characterized by elemental analysis, X- ray dif fract ion, SEM, N2 adsorpt ion and NH3 desorpt ion measurements and thermogravimet ric analysis. Alkylat ion of benzene and other aromat ics by benzyl chloride is invest igated over these sol ids and iron containing microporous aluminophosphates showed both the highest activity and highest selectivity for this reaction. Mössbauer spectroscopy and RPE analysis are investigated to study the isomorphous substitution of Fe, Sn and Co in the aluminophosphate framework and explain the catalytic behaviour of these materials. en_US
