“…[41,42] Besides, Figure 3(c) and Figure S4 showed that the N 1s spectra of all ZnÀ NC catalysts exhibited four characteristic peaks at 398.3, 399.6, 400.6 and 401.7 eV, which could assign to the pyridinic N, pyridonic N/ZnÀ N x , pyrrolic N and graphitic N, respectively. [43,44] As reported, Pyridinic N and Pyridonic N were recognized as the active base-sites for the activation of CO 2 molecules. [45] It was worth noting that the total contents of the active base-sites (Pyridinic N and Pyridonic N) gradually decreased as the temperature rises (Table 1), suggesting that the calcination temperature might presented a negative effect on the catalytic activity.…”

“…Also, the O 1 s spectrum of revealed four types of electron orbits at binding energies of 530.6, 531.6, 532.6 and 533.5 eV (Figure 3(b)), respectively deconvoluted into Zn−O, C=O, O−H and O=C−O [41,42] . Besides, Figure 3(c) and Figure S4 showed that the N 1s spectra of all Zn−NC catalysts exhibited four characteristic peaks at 398.3, 399.6, 400.6 and 401.7 eV, which could assign to the pyridinic N, pyridonic N/Zn−N x , pyrrolic N and graphitic N, respectively [43,44] .

“…Subsequently, the ring‐opening was launched by the nucleophilic attack of Br − toward β ‐C−O bond of the less steric hindrance in the epoxide and constituting an intermediate bromoalkoxy anion (I). Meanwhile, the pyridine N and pyridonic N in Zn−NC‐300 catalyst as the Lewis basic sites operated synergistically to adsorb and activate the acidic CO 2 molecule into carbonate species [44,45,63] …”

Developing carbon‐based catalyst with both high efficiency and stability presents an enticing prospect for CO2 cycloaddition. In this work, zinc‐loaded nitrogen‐rich carbon catalyst (Zn−NC) was fabricated facilely through the wet impregnation and one‐pot pyrolysis method. The Zn−NC coupled with tetrabutylammonium bromide (TBAB) could achieve the high catalytic efficiency with 93% or 98.1% yield of propylene carbonate (PC) in solvent‐free system under mild condition or traditional heating conditions. Excellent recyclability and versatility of Zn−NC catalyst were also observed. Moreover, the influence of calcination temperature on catalyst structure, composition and catalytic performance were investigated, and the catalytic mechanism of CO2 cycloaddition with Zn−NC and TBAB was legitimately proposed. Herein, this work provided a promising and sustainable insights to prepare high‐efficient and low‐cost carbon‐based catalysts for CO2 conversion.

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.

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.
