Abstract

Abstract : A very stable sodium–cadmium metal–organic framework with high volumetric CO2 adsorption capacity and selectivity has been prepared by a fast and easy microwave-assisted method. Abstract : We report on a facile and rapid microwave-assisted method for preparing a sodium–cadmium metal–organic framework (having coordinatively unsaturated sodium ions) that considerably shortens the conventional synthesis time from 5 days to 1 hour. The obtained (Na, Cd)-MOF showed an excellent volumetric CO2 adsorption capacity (5.2 mmol cm −3 at 298 K and 1 bar) and better CO2 adsorption properties than those shown by the same metal–organic framework when synthesized following a more conventional procedure. Moreover, the newly prepared material was found to display high selectivity for adsorption of carbon dioxide over nitrogen, and good regenerability and stability during repeated CO2 adsorption–desorption cycles, which are the required properties for any adsorbent intended for carbon dioxide capture and sequestration (CSS) from the post-combustion flue gas of fossil fuelled power stations.
