Abstract Using X-ray powder diffraction analysis, 27 Al and 31 P magic angle spinning nuclear magnetic resonance, and nitrogen adsorption–desorption, it has been shown that, during the crystallization of AlPO 4 -11 and SAPO-11 molecular sieves, the use of pseudoboehmite as an aluminum source leads to the formation of intermediate phases, which are crystalline aluminophosphates AlPO 4 · 2H 2 O and isostructural silicoaluminophosphates with a mesoporous structure.
