Selective Gas Adsorption and Separation of Carbon Dioxide in Metal-organic Frameworks and Composites

Abstract

The development of improving energy efficiency and developing clean energy is relatively slow, so the efficient separation and storage of carbon dioxide (CO2) gas using some porous materials such as metal-organic frameworks (MOFs) has attracted much attention. This paper mainly focuses on current research and development on carbon dioxide adsorption in MOFs. Initially, the traditional synthesis methods and the new MOF methods in recent years and the activation methods that improve the shortcomings of new methods are all reviewed. Besides, pristine MOFs with adjusting the ligands is also introduced because it is considered an alternative to enhance the adsorptive performance. Furthermore, MOFs incorporated with graphite oxide, carbon nanotubes, activated carbon, zeolites, and ionic liquids to construct composite materials and apply in CO2 are also summarized. Finally, the expectation on this application is also presented.
