Synthesis and Characterization of a New Type of Mesoporous SAPO

Abstract

Abstract: A new type of mesoporous silicoaluminophosphate(SAPO-1) with worm-like structure was synthesized by hydrothermal method with embryonic silicate zeolite as the Si source. The slicoaluminophosphate molecular sieve was characterized by XRD, IR, TEM, SEM, TG and N₂ adsorption/desorption techniques. The results showed that SAPO-1 had a stronger acidity than the empirical SAPO prepared from TEOS. The catalytic reaction results showed that SAPO-1 was more active than conventional SAPO₂.

Key words: Mesoporous silicoaluminophosphate, Worm-like struture, Acidity
