Fig. 5. (a) C₂H₂ adsorption isotherms of Cd at 273, 283 and 298 K. The predicted isotherm was obtained based on the Clausius–Clapeyron equation and isotherms measured at 273, 283, and 298 K. The two dashed lines represent the practical working limits of the charging and discharging pressures. (b) Comparison of the USCs and utilization ratios for C₂H₂ storage parameters of representative MOFs.
