Abstract

Direct air capture (DAC) has shown growing potential in addressing climate challenges, with solid adsorbents being extensively studied. This review firstly categorizes solid adsorbents into physical and chemical types based on adsorption principles, followed by systematic analyses of their CO₂ capture mechanisms, performance metrics, regeneration advancements, and inherent limitations. Subsequently, the review emphasizes the superior applicability of solid amine-based adsorbents in DAC systems, and provides critical evaluations on how adsorbent composition and environmental factors influence their performance, highlighting the promising role of macromolecular amine functionalized three-dimensional mesoporous architectures. Finally, the current research status of DAC cycle technology is comprehensively summarized, and the key challenges impeding industrial implementation of DAC are identified. This review aims to provide strategic guidance for future DAC research directions.

固体吸附剂在空气中直接捕集二氧化碳的研究进展

随着固体吸附剂的广泛研究，直接空气捕获（DAC）在应对气候挑战方面显示出越来越大的潜力。本文首先根据吸附原理将固体吸附剂分为物理吸附剂和化学吸附剂，然后系统分析了它们的CO2捕获机理、性能指标、再生进展和固有局限性。随后，综述强调了固体胺基吸附剂在DAC体系中的优越适用性，并对吸附剂组成和环境因素如何影响其性能进行了关键评估，强调了大分子胺功能化三维介孔结构的前景。最后，全面总结了DAC循环技术的研究现状，指出了阻碍DAC产业化实施的关键挑战。本文旨在为今后DAC的研究方向提供战略指导。
