Metal-Organic Frameworks (MOFs) for CO2 Capture

Abstract

Metal-organic frameworks (MOFs) composed of metal nodes linked by organic linkers are a class of newly developed crystalline hybrid porous solids. In the past few years, MOFs have seen a very rapid development both in terms of synthesis of novel structures and their potential applications in a wide variety of fields. Nearly all metals and a large diversity of organic species can be used to construct MOFs, so that a huge variety of materials of MOFs with different structures and properties are accessible. Due to their uniform yet tunable pore sizes, high-surface areas, and easy pore functionalization, MOFs have emerged as superior porous materials for adsorption and membrane-based applications. Particularly, recent studies have demonstrated that MOFs are perfect and quite promising in CO2 capture. This chapter starts with an introduction of MOFs, including their design and synthesis, structural features, properties, and potential applications. Then, their implementation and performance in CO2 capture-related aspects including selective CO2 adsorption in MOFs, CO2 separation in MOFs, MOF-based membrane for CO2 separation, the design of MOFs for CO2 capture, and computational simulation in MOFs for CO2 capture are discussed.
