Research progress on MOFs for CO2 separation and capture

Abstract

The world's population and economy have grown quickly, which has resulted in significant carbon dioxide emissions. People are concerned about the ensuing climate change and other problems. While there are now technologies that can lower alarming levels of greenhouse gas emissions, carbon dioxide capture is seen to be the most economical solution. Thus, it is essential to create efficient CO₂ capture systems. Metal-organic frameworks (MOFs) have been demonstrated to be the most successful materials for CO₂ collection and adsorption due to their microporous structure and advantageous properties, making them the most promising materials currently on the market. The basic properties of MOFs, such as their large surface area, chemical stability, adjustable pores, and porous structure, are initially outlined in this article. Next, the features of MOFs for separation were presented, particularly how well they could separate CO₂ from gases like hydrogen, natural gas, and flue gas. Lastly, this research highlights the use of chemical functionalization, doping metals, and unsaturated metal centers to improve MOFs' adsorption and CO₂ storage capabilities.
