Modulating acid-base properties of ZIF-8 by thermal-induced structure evolution

A series of mononuclear Zn(II) catalysts, ZIF-8-T, with tuned acid-base property, are obtained through calcination of ZIF-8 at different temperatures (T). Amongst, ZIF-8–610 exhibit the highest catalytic activity in the presence of Lewis acid site of Zn2+, Brønsted acid site of –NH/CH nonbridging linkers, and basic site of N species.
