An imidazolium-functionalized mesoporous cationic metal-organic framework for cooperative CO2 fixation into cyclic carbonate.

ABSTRACT

A mesoporous cationic Cr-MOF, termed FJI-C10, containing imidazolium moieties, Lewis acidic Cr3+ sites and free halogens is constructed for the first time by a topology-guided one-pot synthesis. FJI-C10 exhibits excellent performances in CO2 adsorption (20.2 wt% at 273 K and 1 bar) and chemical fixation of CO2 into cyclic carbonates without the use of co-catalyst under atmospheric pressure.
