Key factors influencing direct CO_(2)capture from airOA
Excessive CO_(2)emission into the atmosphere has caused serious climate change that draws global concerns.Direct air capture(DAC)plays a crucial role in reducing atmospheric CO_(2)concentration and mitigating climate change.In this review,we summarize the latest advances and emerging opportunities in DAC through three key aspects.First,we introduce two different types of air contactors(adsorption-and absorption-based)and their functions,unveiling their critical roles in DAC.Second,we discuss a number of effective capture agents for DAC,including solid adsorbent materials and liquid absorbent solutions,with emphasis on the capture mechanism and efficiency.Third,we present three typical methods for CO_(2)release and capture agent regeneration that match DAC effectively,including temperature swing,precipitation-phase separation,and electrolysis,focusing on the CO_(2)release process and energy consumption.In the end,we provide insights into the existing challenges,potential solutions,and future directions for advancing DAC technologies.
