Binding and separation of CO2, SO2 and C2H2 in homo- and hetero-metallic metal–organic framework materials

MFM-300(Cr) and the mixed-metal MFM-300(Al_0.67Cr_0.33) have been synthesised and characterised; their adsorption isotherms and host–guest interactions with CO₂, SO₂ and C₂H₂ are investigated systematically.
