MOF-74 type variants for CO2 capture

Carbon capture and storage (CCS) is aimed at disposing the carbon dioxide (CO2) generated by power plants. As next-generation adsorbents, metal-organic framework (MOF) adsorbents with high surface area, tunable pore size, and low heat capacity are in the spotlight for CCS applications. Among the known MOFs, MOF-74 type analogs exhibit high CO2 adsorption performance due to the open metal sites in the hexagonal channels aligned along the c-axis. Extensive studies on such adsorbents have been carried out to control CO2 adsorption and enable selective adsorption even under wet conditions. From this perspective, this review addresses not only the CO2 adsorption properties of the MOF-74 type structures, but also their enhanced CO2 capacity through modifications of organic linkers and open metal sites of the frameworks.
