Strategies to Enhance Carbon Dioxide Capture in Metal‐Organic Frameworks

Abstract: The dramatic increase of atmospheric CO2 concentration is responsible for a fast and potentially unpredictable global climate change. Therefore, the implementation of negative carbon technologies such as direct air capture (DAC) is needed. Metal–organic frameworks (MOFs) have the potential to perform CO2 DAC and achieve unprecedented performances. Herein strategies to improve the CO2 capture efficiency of MOFs and their potential implementation in real applications are discussed. Three main categories of targe… Show more

“…Piscopo et al 153 believed that the diamine-functionalized Mg 2 (dobpdc) material was the best choice for CO 2 capture processes based on MOFs so far, which exhibited a very high affinity for CO 2 under extremely low pressure. Because the alkyl group modification improved the hydrophobicity, the CO 2 adsorption capacity remained unchanged after the adsorption/desorption cycles with the actual dilute CO 2 concentration and humidity.…”

“…In CCS, the first step is to capture the CO 2 either from anthropogenic point sources, from bioenergy conversion or from atmosphere by direct air capture to remove current and historical emissions 6,7 . CO 2 adsorption in solid porous sorbents such as carbon 8 , zeolites 9 , covalent-organic polymers 10 , covalent-organic frameworks 11 and metal-organic frameworks (MOFs) 12 has drawn widespread attention due to their low energy requirements 13 . MOFs are nano-and/or mesoporous synthetic crystals, composed of metal ion/oxide nodes coordinated by organic ligands.…”

“…MOFs as the adsorbent may suffer from chemical and mechanical instability, which limits their practical application for CO 2 capture and storage. Combing the structural merits of MOFs and other materials such as chemically stable nanocarbons is a potentially promising solution to address these issues [221,222] . Among these, graphene and its derivates are commonly used as composite component due to the high specific surface area and good compatibility with the metal nodes of the framework [223,224] …”
