Abstract:
1. A method of separating a component gas from a multi-component gas, comprising contacting a functionalized zeolitic framework with the multi-component gas, wherein a component of the multi-component gas is selectively adsorbed to the functionalized zeolitic framework by electrostatically interacting with the one or more electron withdrawing group of the pore walls, thereby separating the absorbed component from other components in the multi-component gas, wherein the functionalized zeolitic framework is ZIF-68, ZIF-69, or ZIF-70, and wherein the method comprises either (a) separating the component gas from a multicomponent gas, where the multicomponent gas is natural gas, or (b) separating the component gas from a multi-component gas that is rich in methane and contains CO
