Abstract: Silicoaluminophosphate zeolite SAPO-34 exhibits excellent performance in adsorption and catalysis due to its unique structure and small diameter. Mesoporous SAPO-34(named as SAPO-34-H) was prepared using a long\|chained organosilane as the only source of silicon and the mesoscale template. SAPO-34-H was  characterized by various techniques. N2 adsorption and TEM images results show that mesopores with a diameter of ca. 5.1 nm exist in the microporous crystals. NH3-TPD results show that the introduction of mesopores results in the decrease of acidity.

Key words: Hierarchical porous material(SAPO-34-H), Micropore, Mesopore
