Escalating carbon dioxide (CO2) emissions have intensified the greenhouse effect, posing a significant long-term threat to environmental sustainability. Direct air capture (DAC) has emerged as promising approach achieving net-zero future, which offers several practical advantages, such independence from specific CO2 emission sources, economic feasibility, flexible deployment, and minimal risk of leakage. The design optimization DAC sorbents are crucial for accelerating industrial adoption. Metal-organic frameworks (MOFs), with high structural order tunable pore sizes, present an ideal solution strong guest-host interactions under trace conditions. This perspective highlights recent advancements in using MOFs DAC, examines molecular-level effects water vapor on capture, reviews data-driven computational screening methods develop molecularly programmable MOF platform identifying optimal sorbents, discusses scale-up cost DAC.

Continuous accumulation and emission into the atmosphere of anthropogenic carbon dioxide (CO2), a major greenhouse gas, has been recognized as primary contributor to climate change associated with global warming acidification oceans. This led drastic changes in natural ecosystem, hence an unhealthy ecological environment for human society. Thus, effective mitigation ever increasing CO2 most important challenge. To achieve zero footprint, novel materials approaches are required potentially reducing release, while our current fossil-fuel-based energy must be replaced by renewable free from emissions. In this paper, porous carbons hierarchical pore structures promising adsorption electrochemical reduction owing their high specific surface area, excellent catalytic performance, low cost long-term stability. Since efficient gas-phased (electro)catalysis involves access reactants active sites at gas-liquid-solid triple phase, possess multiple advantages various CO2-related applications enhanced volumetric gravimetric activities (e.g., uptake density) practical operations. Recent studies have demonstrated that exhibited notable adsorbents provided facile conducting pathways mass diffusion channels even under operation conditions. Herein, we summarize recent advances capture, storage, conversion. Prospectives challenges on rational design scalable capture conversion also discussed.

Rising CO2 emissions are responsible for increasing global temperatures causing climate change. Significant efforts underway to develop amine-based sorbents directly capture from air (called direct (DAC)) combat the effects of However, sorbents' performances have usually been evaluated at ambient (25 °C) or higher, most often under dry conditions. A significant portion natural environment where DAC plants can be deployed experiences below 25 °C, and always contains some humidity.

Previous research has demonstrated that amine polymers rich in primary and secondary amines supported on mesoporous substrates are effective, selective sorbent materials for removal of CO2 from simulated flue gas air. Common used include alumina silica (such as SBA-15 MCM-41). Conventional microporous generally less since the pores too small to support low volatility amines. Here, we deploy our newly discovered zeolite nanotubes, a first-of-their-kind quasi-1D hierarchical zeolite, substrate poly(ethylenimine) (PEI) capture dilute feeds.
