Abstract: Thermodynamic analysis of gate-opening carbon dioxide (CO2) adsorption behavior of metal-organic frameworks (MOFs) was investigated using differential scanning calorimetry (DSC). Unlike measurements under nitrogen atmosphere, obvious exothermic and endothermic peaks were observed in DSC curves… read more here.
