Electrostatically Driven Selective Adsorption of Carbon Dioxide over Acetylene in an Ultramicroporous Material.

ABSTRACT: Separating acetylene from carbon dioxide is important but highly challenging owing to their similar physical properties and molecular dimensions. Herein, we report highly efficient electrostatically driven CO₂ /C₂ H₂ separation in an ultramicroporous cadmium nitroprusside (Cd-NP) with compact pore space and complementary electrostatic potential well fitting for CO₂ , thus enabling molecular quadrupole moment recognition of CO₂ over C₂ H₂ . This material shows a high CO₂ /C₂ H₂ uptake ratio of 6.0 as well as remarkable CO₂ /C₂ H₂ selectivity of 85 under ambient conditions with modest CO₂ heat of adsorption.
