Abstract: The zeolite Pcontaining phosphorus and SAPO-20 molecular sieve were synthesized by hydrothermal crystallization with H3PO4, boehmite and colloidal silica in the presence of HF and TMAOH as the template.The crystallization fields of the two molecular sieves were obtained by changing the contents of P, Al and Si in the reactants.The ways of heteroatom substitution were investigated by 31P and 29Si MAS NMR technique.

Key words: Molecular sieve, Zeolite-P, SAPO-20, Hydrothermal crystallization, 1H NMR
