SAPO-34 and ZSM-5 nanocrystals’ size effects on their catalysis of methanol-to-olefin reactions

[Display omitted] ► Four catalysts each of 20–5000nm SAPO-34 and ZSM-5 were prepared. ► The smallest (5000nm) catalysts also exhibited poor catalytic activity. ► The catalyst with moderate crystallites (200–500nm) show high catalytic activity. ► Extremely small nanocrystallites (
