A Review on Removal of Carbon Dioxide (CO2) using Zeolitic Imidazolate Frameworks: Adsorption and Conversion via Catalysis

Abstract

Carbon dioxide (CO2) is one of the culprit causes of global climatic changes. Furthermore, the efficient separation of CO2 from other gaseous mixtures using ZIFs-based materials is vital for several processes such as flue gas separation, gas sweetening, and natural gas processing. Zeolitic imidazolate frameworks (ZIFs)-based materials are emerging adsorbents and catalysts for CO2 gas removal via adsorption and conversion into valuable chemicals. ZIFs-based adsorbents with high adsorption/conversion efficiencies and tunable properties can be achieved by judicious synthesis and fabrication methods. We reviewed ZIF-based materials for CO2 removal via adsorption and catalysis (e.g., cycloaddition, carboxylation, hydrogenation, N-formylation, electrocatalysis, and photocatalysis). In addition, recent development methods such as membrane synthesis and ways to improve the gas separation performance of ZIF membranes were highlighted. The prospective point of view to promote industrial applications and commercialization of ZIF-based materials was briefly discussed. Once challenges such as low performance and reproducibility for ZIFs-based materials are solved, scalability and cost-effectiveness should not become issues.

Biodegradable Polymer Nanocomposites

“…There are three main steps for polymerization: initiation, propagation, and termination. MOFs are coordination polymer formed via self-asselmbly of metal ions and organic linkers [28,42,43,49,51,52,58,65,66,155]. They can be decomposed into their constituent in harsh consition i.e.…”

Advanced Multifunctional Materials (2023)

“…The generated hydrogen can be used for dye degradation [182]. ZIFs-based materials were reviewed as efficient adsorbents and catalysts for CO2 removal via adsorption and conversion into value-added compounds [184][185][186][187][188]. ZIF-8 and ZIF-67 can be in-situ grown into cellulosic filter paper that was used as an efficient catalyst for the reduction of water pollutants such as nitrophenols [189].…”
