We show structures and isotherm information for these 4 MOFs inFigure S8. The isotherm plots include the simulated CO 2 and N 2 adsorption capacities for these MOFs at multiple pressures and 4 different temperatures. The fitted isotherm model is shown on the same plot. Goodness of fit (Root Mean Square Error -RMSE) is used to The higher performing MOFs VASFON and MOCHIW, have significant capacity at 0.041 bar of CO 2 partial pressure while MOFs BETGUE and EVOMOR have lower CO 2 adsorption capacity at lower partial pressures.
