A new honeycomb metal–carboxylate-tetrazolate framework with multiple functions for CO2 conversion and selective capture of C2H2, CO2 and benzene

A stable Cd-MOF was built by a carboxylate-tetrazolate ligand, which contains hexagonal channels and reveals multiple functions including separation of CO₂/CH₄, C₂H₂/CO₂, C₂H₂/CH₄ and benzene/cyclohexane, and catalytic conversion of CO₂ with epoxides.
