Enzymatic electrosynthesis offers a novel approach to the production of chemicals through CO 2 sequestration. In this mini-review, we present the most recent state-of-the-art information on enzymatic CO 2 reduction for the production of chemicals such as formic acid using oxidoreductase (single or multiple) enzymes as electrocatalysts in enzymatic electrosynthesis cell (EEC). Key challenges towards upscaling of this CO 2 utilization approach are identified and future research directions are discussed briefly.

“…Recently, an innovative approach for greatly reducing heat duty of amine solvent regeneration was proposed in our earlier works. , The use of acid catalysts for the CO 2 desorption process mainly decreases the sensible heat and evaporation heat by donating the proton to aid the breakdown of carbamate and lowering the desorption temperature from 120 to 140 °C to a temperature less than 100 °C. , The results demonstrated that the introduction of the solid acid catalysts into the rich amine solvent could significantly reduce the energy requirement. Various solid catalysts, such as zeolites, metal oxides, sulfated metal oxides, carbonic anhydrase, and metal modified zeolites, have been evaluated for this objective. ,,,− A brief review of investigations for the catalytic rich MEA solution regeneration process over solid acid catalysts is summarized in Table S3. Note that compared with the catalyst-free run, the addition of the different solid acid catalysts with 5 M MEA lowered the energy consumption by approximately 10–34% and increased the quality of released CO 2 by approximately 10–94%, respectively.…”

The high energy consumption of CO2-loaded solvent regeneration is the biggest impediment for the real application of the amine-based CO2 capture process. To lower the energy requirement, three Fe promoted SO4 2–/ZrO2 supported on MCM-41 (SZMF) catalysts with different iron oxide content (5%, 10%, and 15%) were synthesized and applied for the rich monoethanolamine solution regeneration process at 98 °C. Results reveal that the use of SZMF hugely enhanced the CO2 desorption performances (i.e., desorption factor) by 260–388% and reduced the heat duty by about 28–40%, which is better than most of the reported catalysts for this purpose. The eminent catalytic activities of SZMF are related to their enhanced ratio of Brønsted to Lewis acid sites, weak acid sites, basic sites, and high dispersed Fe3+ species. Meanwhile, the addition of SZMF for CO2 desorption shows a promotional effect on its CO2 absorption performance, and SZMF presents an excellent cyclic stability. A possible mechanism is suggested for the SZMF catalyzed CO2 desorption process. Results of this work may provide direction for future research and rational design of more efficient catalysts for this potential catalyst-aided CO2 desorption technology.

High heat duty is an urgent challenge for industrial applications of amine‐based CO2 capture. The temperature (>110°C) of carbamate breakdown in amine regeneration requires large energy consumption. In this work, we report a novel, stable, efficient, and inexpensive Ni‐HZSM‐5 catalyst to improve the CO2 desorption rate and reduce the heat duty. The impregnation method was applied for varying nickel content in the catalysts from 2.16 to 9.80 wt% in HZSM‐5. The catalysts were characterized by scanning electron microscope, X‐ray powder diffraction, N2 adsorption–desorption, inductively coupled plasma‐optical emission spectrometry, ultraviolet‐visible diffuse reflectance spectroscopy, X‐ray photoelectron spectroscopy, NH3‐temperature programmed desorption (TPD), Infrared spectroscopy of pyridine adsorption, and Fourier transform infrared spectroscopy. The catalytic performance was evaluated by CO2 desorption of rich amine solvent at 90°C. It was found that the introduction of nickel increased the acid sites of catalysts compared with parent HZSM‐5. This phenomenon plays a key role on improving the CO2 desorption rate. The density functional theory (DFT) calculations successfully explain the catalytic performance. The catalytic activity associates with the combined properties of MSA × B/L × Ni2+. The 7.85‐Ni‐HZ catalyst presents an excellent catalytic activity for the CO2 desorption: it increases the amount of desorbed CO2 up to 36%, reduces the relative heat duty by 27.07% with the same reaction time, and possesses high stability during five cyclic tests. A possible catalytic mechanism for the Ni‐HZSM‐5 catalysts through assisting carbamate breakdown and promoting CO2 desorption is proposed based on experimental results and theoretical calculations. Therefore, the results present that the 7.85‐Ni‐HZ catalyst significantly accelerates the protons transfer in CO2 desorption and can potentially apply in industrial CO2 capture.
