Figure 3 GCMC-Simulated Arrangement of Binary Mixtures on kag-MOF-1 at 303 K Snapshots obtained during GCMC simulated arrangements of CO2 and N2 molecules (A) and CO2 and CH4 molecules (B) from binary-mixture simulations on kag-MOF-1 (CO2/N2 and CO2/CH4 with molar compositions of 10/90 and 5/95, respectively, at 303 K). The interacting distances are reported in Ångströms, and the atoms are represented as follows: carbon, gray; nitrogen, blue; hydrogen, white; oxygen, red; zinc, magenta; and methane, green.
