| This review critically evaluates recent advances in solid and structured sorbents for CO₂ capture, emphasizing the link between material properties, structured geometry, regeneration, and process performance. Representative sorbent classes typically achieve 2-6.8 mmol/g CO₂ uptake for zeolites and carbons, while selected MOFs can reach higher gravimetric capacities under favorable laboratory conditions; these values are not directly comparable due to differences in temperature, pressure, humidity, gas composition, and active-phase loading. In structured systems the principal advantage is often reduced pressure drop, improved heat and mass transfer, and higher reactor-level efficiency rather than higher intrinsic gravimetric capacity. A recent techno-economic analysis of a DAC monolith showed substantially lower fan work than a packed bed owing to an approximately two-order-of-magnitude reduction in pressure drop, although the packed bed exhibited higher reference productivity (2.4 versus 1.2 kg CO₂/ m3h) and the modeled capture cost remained above 1500 € per tonne of CO₂ at a capture scale of 100 kt CO₂/yr. Electrified regeneration routes, including resistive/electrothermal swing adsorption, microwave, and induction heating, enable rapid and localized heating but face challenges in temperature uniformity, electrical-to-thermal efficiency, materials compatibility, and scale-up. The review argues that adsorbent selection should prioritize working capacity, impurity tolerance, regeneration energy, cyclic stability, pressure drop, volumetric productivity, and cost rather than maximum equilibrium capacity alone. Application-specific criteria are proposed for post-combustion capture, direct air capture, and biogas upgrading, together with research priorities for realistic multicomponent testing and integrated material-process optimization. | ||
