Carbon dioxide capturing activities of porous metal-organic frameworks (MOFs)

Abstract

Global warming has become a critical concern that affects the whole ecology and affects greenhouses in the environment. Therefore, there is a great need to design and create new materials for capturing gases to reduce their environmental effects. The porous nature of metal-organic frameworks (MOFs) has emerged as promising gas adsorption and separation candidates and helps reduce global warming by capturing harmful gases like CO2, N2O, CO, etc. In this review, we have discussed a critical idea for MOF gas adsorbents with insights into the development, synthesis, and structural properties. Moreover, the key factors responsible for gas adsorption and hydrophobicity for fluid gas adsorption are discussed. Furthermore, some recent advances regarding MOFs for CO2 adsorption/separation have been elucidated in detail. In addition, MOF gas capturing properties and the effect of pore size, surface area, faradaic efficiency, and maximum CO2 uptake are concluded. The study will open a new pathway for researchers to design and develop efficient gas-capturing materials.
