“…For the past decade, various Lewis acid catalysts have been developed for the reductive carbon dioxide fixation to formamides. − ,− For example, homogeneous catalysts bearing Zn, Cu, and Fe have been reported with TONs of 30–198 and TOFs of 1–33 h –1 for the reductive carbon dioxide fixation with N -methyl- N -phenylamine to N -methyl- N -phenylformamide at temperatures of 25–60 °C (refer to Table S2 for recent homogeneous catalytic systems). − …”

“…Recently, new heterogeneous catalysts have been developed with TONs of 9–70 and TOFs of 1–3 h –1 for the reductive carbon dioxide fixation with N -methyl- N -phenylamine or aniline to N -methyl- N -phenylformamide or N -phenylformamide at temperatures of 25–130 °C (refer to Table S3 for the performance survey of recent heterogeneous catalytic systems). − Especially, Zn-based heterogeneous catalysts have shown TONs of 14–40 and TOFs 1–2 h –1 for the reductive carbon dioxide fixation with N -methyl- N -phenylamine to N -methyl- N -phenylformamide at temperatures of 60–120 °C (refer to Table S4 for recent Zn-based heterogeneous catalytic systems). − Thus, further exploration of more efficient heterogeneous catalytic systems is required. In this regard, the H-MOP@ZnG-2 showing a TON of 97 and a TOF of 8 h –1 at room temperature is quite promising.…”

“…Recently, the reductive carbon dioxide fixation to formamides has attracted significant attention from scientists due to its mild reaction conditions. − The reaction of carbon dioxide with amines in the presence of silanes can induce the formation of formamides. Efficient Lewis acid catalysts enable this conversion to take place even at room temperature. − …”

This work suggests an engineering methodology for catalytic 2D materials to achieve more efficient catalytic systems. Zinc gallate (ZnG), a Lewis acidic material with a thin 2D morphology, can easily form aggregates through layer–layer packing. Inner parts of ZnG aggregates would have difficulty in interacting with substrates. By coating hollow microporous organic polymer (H-MOP) supports with ZnG, the catalytic performance of ZnG can be enhanced due to facilitated contact of substrates with Zn species in shells. H-MOP@ZnG-2 with an optimal ZnG coating showed a much enhanced catalytic performance for the reductive carbon dioxide fixation with amines to formamides compared with ZnG. Various amines can be utilized in the reductive carbon dioxide fixation to formamides. In addition, H-MOP@ZnG-2 showed recyclability, maintaining its catalytic performance for five successive reactions.

“…The possible reason is that a high pressure resulted in a low phenol concentration in the liquid phase because of the dilution by CO 2 dissolution, and such an effect of the CO 2 pressure on the catalytic activity was also reported for the synthesis of cyclic carbonate from epoxide and CO 2. − Thus, the optimal pressure was 0.20 MPa.…”

Diphenyl carbonate (DPC) has outstanding practical potential, especially as a key building block for the phosgene-free synthesis of polycarbonate (PC) in the chemical industry. The synthesis of DPC from CO 2 has been investigated for decades, but exploring highly efficient catalytic systems is still challenging. Herein, an efficient catalytic system for the direct synthesis of DPC from CO 2 , phenol, and carbon tetrachloride was developed by using a ZnCl 2 / copper triflate (Cu(OTf) 2 ) composite catalyst. For the first time, high yield and high selectivity were achieved for DPC synthesis under mild conditions, even at atmospheric pressure. Carefully designed control experiments and DFT studies indicated that the synergistic activation of Cu(OTf) 2 and its anion complex with ZnCl 2 for phenol and CO 2 led to a remarkably improved catalytic activity through a Lewis acid-assisted catalysis. This study not only provides a new strategy for efficient preparation of DPC but also offers an effective pathway for better CO 2 utilization.

As the ultimate carbon emission of the combustion process, carbon dioxide (CO2) is a serious environmental hazard in increasing the global climate temperature through the greenhouse effect. Porous heterogeneous catalysts have drawn huge interest for carbon capture and in the past decades; significant developments can be observed in their fabrication and implementation for CO2 capture and conversion. In this context, the emerging development in major porous heterogeneous catalysts such as MOFs, COFs, metal oxides etc. for CO2 capture and conversion are discussed. Their physiochemical properties and their influence on the efficiency for CO2 capture and conversion are enlightened. The review provides a concise report on various types of heterogeneous catalysts, current trends, their application in CO2 reduction and fixation for the synthesis of fuels and other important fine chemicals and future research directions for the deployment of porous heterogeneous catalysts in Carbon dioxide capture and conversion.
