Carbon Dioxide Capture in Metal-Organic Framework

Abstract

The greatly risen level of atmospheric carbon dioxide after the industrial revolution leads to serious problems and concerns, including health issues and global warming. Therefore, the significance of carbon dioxide capture can not be overemphasized. Metal-organic framework (MOF), a brand-new and potential kind of material, can be utilized in several processes of CO2 capture because of its high capacity as well as high selectivity. In this review, the key parameters for evaluation of the MOF used for CO2 capture, which is directed related to the performance of materials, are addressed and discussed. Several important and practical evaluation indicators are also mentioned, for economic cost and stability, and tolerance to impurity. Additionally, factors that affect the performance of CO2 adsorption in both structural and external degrees of MOF are shown and reviewed. This article provides a different perspective of parameters for MOF materials and indicates critical features for the organic linkers and metal ions that are used to build the whole framework.
