Global climate change is the biggest threat to the sustainable development of human, and controlling CO2 emissions is a major measure to deal with climate change. As a negative emission technology, the direct air capture (DAC) can capture CO2 emitted 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.
