Enhanced CO2 capture capacities and efficiencies with N-doped nanoporous carbons synthesized from solvent-modulated, pyridinedicarboxylate-containing Zn-MOFs

Abstract

This paper describes the pyrolysis of pyridinedicarboxylate-containing Zn-based metal–organic frameworks (MOFs) to form nanoporous carbons with accessible N dopants to adsorb CO₂. The optimal materials were synthesized using N-heterocycle additives to control the amount of coordinated DMF in the base MOF structure, thereby increasing its thermal stability prior to pyrolysis.
