مستخلص: The increase in the atmospheric carbon dioxide level is a significant threat to our planet, and therefore the selective removal of CO 2 from the air is a global concern. Metal-organic frameworks (MOFs) are a class of porous materials that have shown exciting potential as adsorbents for CO 2 capture due to their high surface area and tunable properties. Among several implemented technologies, direct air capture (DAC) using MOFs is a promising strategy for achieving climate targets as it has the potential to actively reduce the atmospheric CO 2 concentration to a safer levels. In this study, we investigate the stability and regeneration conditions of N , N '-dimethylethylenediamine (mmen) appended Mg 2 (dobpdc), a MOF with exceptional CO 2 adsorption capacity from atmospheric air. We employed a series of systematic experiments including thermogravimetric analysis (TGA) coupled with Fourier transformed infrared (FTIR) and gas chromatography mass spectrometer (GCMS) (known as TGA-FTIR-GCMS), regeneration cycles at different conditions, control and accelerated aging experiments. We also quantified CO 2 and H 2 O adsorption under humid CO 2 using a combination of data from TGA-GCMS and coulometric Karl-Fischer titration techniques. The quantification of CO 2 and H 2 O adsorption under humid conditions provides vital information for the design of real-world DAC systems. Our results demonstrate the stability and regeneration conditions of mmen appended Mg 2 (dobpdc). It is stable up to 50% relative humidity when the adsorption temperature varies from 25-40 °C and the best regeneration condition can be achieved at 120 °C under dynamic vacuum and at 150 °C under N 2 .
