Fig. 2. CO2 uptake in tetraamine-appended Mg2(dobpdc).

Fig. 2.

(A) Adsorption isobars obtained through thermogravimetric analysis of Mg2(dobpdc)(tetraamine) under pure CO2 at atmospheric pressure. Dashed lines indicate the theoretical capacities for binding of one and two CO2 molecules per tetraamine. (B) Adsorption (filled circles) and desorption (open circles) isotherms for CO2 uptake in Mg2(dobpdc)(3–4-3) at 90°, 100°, 110°, and 120°C. The CO2 pressures in an untreated NGCC flue emission stream (40 mbar) and following 90% capture (4 mbar) are indicated by light gray and dark gray lines, respectively.
