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.

Carbon dioxide (CO2) is one of the culprit causes of global climatic changes. Furthermore, the efficient separation of CO2 from other gaseous mixtures using zeolitic imidazolate framework (ZIF)‐based materials is vital for several processes such as flue gas separation, gas sweetening, and natural gas processing. ZIF‐based materials are emerging adsorbents and catalysts for CO2 gas removal via adsorption and conversion into valuable chemicals. ZIF‐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 technologies 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 ZIF‐based materials are solved, scalability and cost‐effectiveness should not become issues.

“…According to previous reports, there are many Cu-based materials to enhance the activity of the catalysts in CO 2 reduction, including oxide-derived Cu, Cu-based alloys, Cu single atoms, Cu-MOF materials, etc. − Among these materials, MOF materials have been widely studied due to the high dispersion of metal sites and the tunability of ligands. − In addition, numerous studies have found that the Cu-based nanoclusters of mixed Cu + /Cu 0 states are more favorable for the adsorption of CO 2 reduction intermediates, which can effectively convert CO 2 into C 2+ products. − Recently, highly active Cu-based nanoclusters can be synthesized through the preactivation of MOFs containing Cu–O 4 nodes, which not only improves product selectivity but also greatly enhances the current density. For example, Cao’s group constructed the single-type Cu 2 O (111) site on CuHHTP by preactivation.…”

In Situ Reconstruction of Cu–N Coordinated MOFs to Generate Dispersive Cu/Cu₂O Nanoclusters for Selective Electroreduction of CO₂to C₂H₄

Electrochemical reduction of CO2 to obtain high-value-added feedstocks is a promising strategy to alleviate the energy crisis. Cu-based catalysts generate multi-carbon products with high activity in the CO2 reduction reaction (CO2RR), although great challenges remain in the selectivity and stability of Cu-based catalysts. Here, highly active Cu/Cu2O nanoclusters were produced via in situ electrochemical reconstruction using Cu–N coordinated MOFs as precursors for the highly selective C2H4 synthesis, showing a Faradaic efficiency of 70.2 ± 1.7% toward C2H4 with a partial current density of 12.38 mA·cm–2 at −1.03 V vs RHE in the CO2RR. In situ infrared spectroscopy with the observation of *CO*CO and *CO*COH intermediates confirmed the C2H4 formation pathway, while in situ Raman spectroscopy, ex situ XPS, and HRTEM evidenced that the coexisting Cu2O and Cu nanoclusters were the active sites. The in situ reconstruction method could be used to synthesize catalysts with high activity and selectivity for CO2 electroreduction.
