CO 2 Capture and Separation of Metal–Organic Frameworks

Abstract

This chapter introduces CO2 capture and separation related to metal–organic framework (MOF) materials. The concentration of CO2 in the atmosphere has increased rapidly from 310 to 411 ppm over the period 1960–2019 and is expected to reach more than 500 ppm by 2050. The chapter provides an overview of work in this area and considers the evaluation of the adsorption process and its selectivity using the isosteric heat of adsorption and ideal adsorbed solution theory. It also provides a summary of capture technologies and MOFs as a promising candidate for CO2 separation and capture. The chapter outlines the mathematical methods to evaluate the performance of practical gas separation. It illustrates the ability of MOFs in CO2 capture and separation. The chapter discusses CO2 capture based on MOFs ability and the relevant evaluation theory. It concludes with the improvement of the MOF structure and future study for CO2 capture.
