Abstract
As an emerging carbon capture method,direct air capture(DAC)technologydirectly captures carbon dioxide(CO2)from the atmosphere,effectively reducing CO2 concentration in the atmosphere.Therefore,DAC provides important technical support for achieving the global vision of carbon neutrality.The article analyzed the basic principles,methods,and application status of DAC technology.Additionally,it mainly introduced different types of adsorbents for DAC,including alkali/alkaline metal-based adsorbents,amine-modified porous materials,ionic liquid-based porous materials,metal-organic frameworks,and covalent organic framework materials.The advantages and disadvantages of these adsorbents during DAC were explored by the performance evaluation of existing solid DAC adsorbents in adsorption capacity,selectivity,cycle stability,and thermal stability.关键词
