Global atmospheric CO₂ concentrations have risen persistently to record highs, making the deployment of negative-emission technologies critical for meeting global climate goals. Among carbon management strategies, direct air capture (DAC) is a prominent negative-emission technology for removing CO₂ directly from the atmosphere, but its development is limited by the need for adsorbents that have high CO₂ capture efficiency, excellent selectivity, and low energy requirements for regeneration. Biomass-derived carbon materials have emerged as ideal candidates for DAC adsorbents due to their renewable feedstocks, low cost, adjustable structures, and natural carbon-negative potential. This review systematically outlines the core performance metrics of DAC adsorbents, covering the preparation of biomass-derived carbon, key factors influencing CO₂ capture performance, and related tuning strategies.
