Selective Adsorption of CO2 from Light Gas Mixtures by Using a Structurally Dynamic Porous Coordination Polymer

摘要

Gas separations are important to many diverse areas of fossil energy including pre- and post-combustion CO2 capture and fuel cell applications. The need for efficient gas purification processes has led to interest in adsorption-based separations and new sorbent materials. Porous coordination polymers (PCPs), commonly referred to as metal-organic frameworks (MOFs), lend a great deal of structural versatility to such applications. A combination of organic and inorganic building blocks, these multi-dimensional hosts can be tailored for selective adsorption of one guest over another through methods such as pore-size exclusion, mesh-size adjustable sieving, and guest-dependent structural dynamics.
