Adsorptive Separation of CO 2 by a Hydrophobic Carborane-Based Metal-Organic Framework under Humid Conditions.

We report that the carborane-based metal-organic framework (MOF) m CB-MOF-1 can achieve high adsorptive selectivity for CO 2 :N 2 mixtures. This hydrophobic MOF presenting open metal sites shows high CO 2 adsorption capacity and remarkable selectivity values that are maintained even under extremely humid conditions. The comparison of m CB-MOF-1' with MOF-74(Ni) demonstrates the superior performance of the former under challenging moisture operation conditions.
