Polyethyleneimine templated synthesis of hierarchical SAPO-34 zeolites with uniform mesopores

Abstract

SAPO-34 zeolites with uniform mesopores have been successfully synthesized using polyethyleneimine (PEI) dendrimer as co-template through conventional hydrothermal synthesis for microporous crystalline SAPO-34. This series of SAPO-34 possesses higher BET specific surface area (as high as 560 m2 gāˆ’1) and larger mesoporous volume (as large as 0.27 cm3 gāˆ’1). The size and volume for the mesopores can be adjusted by the molecular weight and the amount of the PEI added. The hierarchical SAPO-34 would be a potential industrial catalyst for methanol-to-olefin (MTO) and methanol-to-propylene (MTP) conversions.
