An amine-functionalized metal organic framework for preferential CO_2 adsorption at low pressures

摘要

A metal organic framework with amine-lined pores gives high values for surface area and heat of adsorption with CO_2 gas.rnMetal organic frameworks (MOFs) show great promise for gas sorption and storage. For carbon dioxide, notable advances have occurred with respect to both capacity (MOF-177 is capable of storing up to 33.5 mmol g~1 of CO_2~3) and demonstrating the ability of MOFs to separate CO_2 from mixtures of gases. While large pore MOFs could be effective for storing high capacities of the gas, usually at higher pressures, they may not be as efficient at lower pressures.
