Fig. 4. Low-pressure gas adsorption isotherms for CO (yellow),40 CO2 (green),29 CH4 (gray), N2 (dark blue), O2 (red), and Ar (light blue) at 298 K (left). High-pressure gas adsorption isotherms for CO (yellow),40 CO2 (green), CH4 (gray), N2(dark blue), and Ar (light blue) at 298 K (right). The filled circles and solid lines represent experimental data and corresponding Langmuir fits, respectively.
