摘　　要：全球气候变化是对人类可持续发展的最大威胁,控制CO排放是应对气候变化的主要举措。直接空气捕集(direct air capture,DAC)技术作为一种负排放技术,能够对交通、农林、建筑行业等分布源排放的CO进行捕集。DAC材料的性能及成本是决定DAC技术能否实现大规模应用的最主要因素。综述了DAC材料的技术发展现状,总结了化学吸收材料、化学吸附材料、物理吸附材料和双功能碳捕集材料的性能指标和优缺点,并对不同的DAC材料进行了技术经济性分析,指出开发低成本、高通量、高选择性、高稳定性的碳捕集材料是实现DAC技术规模化应用的关键。Global climate change is the biggest threat to the sustainable development of human, and controlling COemissions is a major measure to deal with climate change. As a negative emission technology, the direct air capture(DAC)can capture COemitted from distributed sources, such as transportation, agriculture, forestry, and construction industries. The performance and cost of DAC materials are the most important factors that determine the widespread application of DAC technology. This paper reviewed the current research and development status of DAC materials.The performances, advantages and disadvantages of chemical absorption materials, chemical adsorption materials,physisorption materials and multifunctional carbon capture materials were summarized. The techno-economic analysis of different DAC materials was carried out. It is pointed out that the development of carbon capture materials with low cost,high capacity, high selectivity, and high stability is the key to realize the large-scale application of DAC technology.
