Efficient post-synthesis of hierarchical SAPO-34 zeolites via organic amine etching under hydrothermal conditions and their enhanced MTO performance

Author affiliations

Abstract

Hierarchical silicoaluminophosphate SAPO-34 zeolites with larger secondary pores were successfully prepared using a chemical etching route with triethylamine (TEA) aqueous solution under hydrothermal conditions. In comparison with their parent counterpart, the obtained hierarchical SAPO-34 zeolites exhibited a similar chemical composition and showed remarkably enhanced catalytic lifetime and selectivity in the MTO reaction.
