“…Obtained CO 2 uptake of the SS-NACF is comparable to the previously reported carbonaceous adsorbents. For instance, the uptake at 25 • C was higher than CFC54 [35], CFS60 [35], CFCMS [36], AKFs6 [37], CP-AC [38], KOH:CWG-22_850 = 1 [39], K 2 CO 3 : CWG-22_850 = 4 [39], AC-50 [40] and comparable or less than K-AC [38], A-PC [41], B-PC [42] and PAB-3 [43]. The detailed comparison for uptake capacity can be seen in Table 1.…”

“…Ahmadi et al 91 successfully fabricated several novel nanoadsorbents as carbon fibers, which were named as CP-AC, J-AC, and K-AC, based on cellulose fibers (cotton, pulp, and kenaf). With the characteristic of a micromesoporous structure, the resultant fibers exhibited high CO 2 adsorption capacity at low pressure.…”

The urgency of curbing global warming triggered by growing CO 2 emissions has generated significant attention. Direct air capture (DAC) is a crucial and feasible technology to cut CO 2 emissions at nonpoint sources, therefore achieving negative emissions. Solid porous sorbents have drawn increasing attention for CO 2 capture from the atmosphere with ultralow CO 2 concentration (ca. 400 ppm). However, most related studies focus on nanoparticle-based adsorbents and their functionalized counterparts, which are more prone to lose weight in the atmosphere. In this context, we summarize nanoparticle composite adsorbents, including zero-dimensional powders, one-dimensional fibers, two-dimensional membranes, and three-dimensional aerogels, and assess the physicochemical properties and typical applications of major types of nanoporous adsorbents in the field of CO 2 adsorption and separation with emphasis on DAC. The multidimensions of emerging adsorbents versus CO 2 uptake are discussed and compared separately. Combined with recent reported advances, we provide deep insights for the design and synthesis of multifunctional materials for efficient CO 2 adsorption. Moreover, life cycle and technoeconomic assessments of DAC using different materials are briefly estimated. Finally, challenges and current trends in the DAC system for commercialization have been put forward.

“…Figure 9B shows a clear trade-off between CO 2 uptake and heat of adsorption. All materials that overcome this bound are nitrogendoped carbons, [33,34,40,60] with two exceptions. The prevalence of nitrogen-doped carbons reflects that selectivity is not taken into account for this bound.…”

“…Of the materials that sit below the 10 kJ mol −1 horizontal bound, none exhibit CO 2 ‐specific interactions. Some report a heat of adsorption greater than 10 kJ mol −1 at low loading (Rb‐MER‐2.3, [ 62 ] SBA‐15, [ 63 ] NUT‐12 [ 64 ] and cellulose fiber carbons [ 60 ] ), some rely on heat of adsorption from temperature dependent isotherm model fits instead of the methods like Clausius‐Clapeyron (ACI granules [ 65 ] and IFP‐7 [ 66 ] ) and most others have a capacity less than 0.5 mol kg −1 (Rb‐MER‐2.3, [ 62 ] Chitosan‐SH, [ 41 ] coals, [ 67,68 ] MWCNTs, [ 69 ] CTF‐NH [ 70 ] and SBA‐15 [ 63 ] ).…”

An Upper Bound Visualization of Design Trade‐Offs in Adsorbent Materials for Gas Separations: CO₂, N₂, CH₄, H₂, O₂, Xe, Kr, and Ar Adsorbents

The last 20 years have seen many publications investigating porous solids for gas adsorption and separation. The abundance of adsorbent materials (this work identifies 1608 materials for CO 2 /N 2 separation alone) provides a challenge to obtaining a comprehensive view of the field, identifying leading design strategies, and selecting materials for process modeling. In 2021, the empirical bound visualization technique was applied, analogous to the Robeson upper bound from membrane science, to alkane/alkene adsorbents. These bound visualizations reveal that adsorbent materials are limited by design trade-offs between capacity, selectivity, and heat of adsorption. The current work applies the bound visualization to adsorbents for a wider range of gas pairs, including CO 2 , N 2 , CH 4 , H 2 , Xe, O 2 , and Kr. How this visual tool can identify leading materials and place new material discoveries in the context of the wider field is presented. The most promising current strategies for breaking design trade-offs are discussed, along with reproducibility of published adsorption literature, and the limitations of bound visualizations. It is hoped that this work inspires new materials that push the bounds of traditional trade-offs while also considering practical aspects critical to the use of materials on an industrial scale such as cost, stability, and sustainability.
