“…Our results are superior to previous results from Hou et al [ 95 ] or Wang et al [ 96 ] ( Supplementary Materials Table S2 ), with the higher CO 2 adsorption achieved by the design CA/MIL-160/Al 2 O 3 membrane being presumably due to the advantages of the design itself which allows for both direct contact of CO 2 with the enzyme as well as hydrophilic wetting through MIL-160. Specifically, Hou et al [ 95 ] reported CO 2 changes at a CA integrated Janus membrane (i.e., carbonic anhydrase (CA)-1H,1H,2H,2H-peruorododecyltrichlorosilane (FTCS)-carbon nanotubes (CNTs)-polyvinylidene fluoride (PVDF)) with authors studying the CO 2 hydration performance when the enzyme was integrated into the hydrophobic polypropylene (PP) hollow fiber membranes.…”

“…Furthermore, Wang’s group achieved high efficiency of CO 2 absorption flux of 2.5 × 10 −3 mol·m −2 ·s −1 , which is considerably reduced when compared to the one achieved in our study. Moreover, in their study the authors immobilized CA onto a polydopamine (PDA)/polyethylenimine (PEI)-polyvinylidene fluoride (PVDF) composite hollow fiber membrane through a crossing linking method [ 96 ], which provides limited scalable capabilities.…”

Carbonic anhydrases are enzymes capable of transforming carbon dioxide into bicarbonate to maintain functionality of biological systems. Synthetic isolation and implementation of carbonic anhydrases into membrane have recently raised hopes for emerging and efficient strategies that could reduce greenhouse emission and the footprint of anthropogenic activities. However, implementation of such enzymes is currently challenged by the resulting membrane’s wetting capability, overall membrane performance for gas sensing, adsorption and transformation, and by the low solubility of carbon dioxide in water, the required medium for enzyme functionality. We developed the next generation of enzyme-based interfaces capable to efficiently adsorb and reduce carbon dioxide at room temperature. For this, we integrated carbonic anhydrase with a hydrophilic, user-synthesized metal–organic framework; we showed how the framework’s porosity and controlled morphology contribute to viable enzyme binding to create functional surfaces for the adsorption and reduction of carbon dioxide. Our analysis based on electron and atomic microscopy, infrared spectroscopy, and colorimetric assays demonstrated the functionality of such interfaces, while Brunauer–Emmett–Teller analysis and gas chromatography analysis allowed additional evaluation of the efficiency of carbon dioxide adsorption and reduction. Our study is expected to impact the design and development of active interfaces based on enzymes to be used as green approaches for carbon dioxide transformation and mitigation of global anthropogenic activities.

“…A lab-scale membrane contactor module was assembled with five pieces of HFs sealed into a PTFE tubing with an effective length of 11 cm and an effective membrane area of 25 cm 2 . The operation of the membrane contacting process for CO2 absorption can refer to the previous report [42,43]. The feed gas (pure CO 2 or biogas) flowed in the lumen side of the HF membranes, and the liquid absorbent (DI water or 1M MEA) counter-currently flowed over the out side of the HFs.…”

“…Successful intensifications of gas/liquid membrane contactors have been developed and employed providing the guideline to the judicious choice of membrane materials [9] and absorbents for CO 2 absorption processes [10,11]. Previous studies proved some durable and reusable materials used for the membrane contactor of CO 2 absorption, where the as-prepared hydrophobic polymethylsilsesquioxane (PMSQ) aerogels [12], and hybrid bis(trimethoxysilyl)hexane (BTMSH)/tetraethyl orthosilicate (TEOS) silica aerogels [13] and highly porous polyvinylidene fluoride (PVDF) [14] were used as a membrane contactor indicating a decrease in the mass-transfer resistance for CO 2 absorption performance. Moreover, the separation efficiency of membrane gas absorption depends on the distribution coefficient and a composition gradient of gas solute in the gas/liquid system [15].…”

The CO2 absorption rate by using a Monoethanolamide (MEA) solution through the spiral wired channel in concentric circular membrane contactors under both concurrent-flow and countercurrent-flow operations was investigated experimentally and theoretically. The one-dimensional mathematical modeling equation developed for predicting the absorption rate and concentration distributions was solved numerically using the fourth Runge–Kutta method under various absorbent flow rate, CO2 feed flow rate and inlet CO2 concentration in the gas feed. An economical viewpoint of the spiral wired module was examined by assessing both absorption flux improvement and power consumption increment. Meanwhile, the correlated average Sherwood number to predict the mass-transfer coefficient of the CO2 absorption mechanisms in a concentric circular membrane contactor with the spiral wired annulus channel is also obtained in a generalized and simplified expression. The theoretical predictions of absorption flux improvement were validated by experimental results in good agreements. The amine solution flowing through the annulus of a concentric circular tube, which was inserted in a tight-fitting spiral wire in a small annular spacing, could enhance the CO2 absorption flux improvement due to reduction of the concentration polarization effect. A larger concentration polarization coefficient (CPC) was achieved in the countercurrent-flow operations than that in concurrent-flow operations for various operations conditions and spiral-wire pitches. The absorption flux improvement for inserting spiral wire in the concentric circular module could provide the maximum relative increment up to 46.45%.
