Metal–organic framework-assisted synthesis of Zr-modified SAPO-34 zeolites with hierarchical porous structure for the catalytic transformation of methanol to olefins

Zr-Modified SAPO-34 zeolites with hierarchical porous structure were synthesized in the presence of UiO-66. The Zr 0.50 -SAPO-34 zeolites exhibited long lifetimes (>1500 min) and excellent selectivity for light olefins (98.66%) in the MTO reaction.
