Metal-Organic (MOF) and Covalent-Organic (COF) Frameworks: Review of Methane, Hydrogen and Carbon Dioxide Adsorption

Storage of methane and hydrogen as clean fuels in transportation section and separation of carbon dioxide due to its destructive effects on environments, are very interesting subjects among academic and industrial researches. Storage and separation of these gases on new types of adsorbents named MOF and COF have been widely studied in recent years. Besides having several desirable specifications of conventional adsorbents (such as activated carbon), these new adsorbents are more appropriate in terms of adsorption of special gases such as methane, hydrogen and carbon dioxide. In the present paper, various types of MOF and COF and their performances in adsorption and storage of the above mentioned gases are reviewed. The ability of producing these adsorbents in our country is also discussed.
