Abstract: This article reviews the current research status of moisture swing sorbents for CO₂ capture in the air. Moisture swing sorbents are a new type of adsorbent with water as the main energy source. It can directly capture CO₂ in the air, reduce the concentration of CO₂ in the atmosphere, break through traditional thermal and temperature regeneration methods, and provide a new approach to alleviate global warming. This material has been extensively studied by researchers in the past two decades. The development of high adsorption capacity materials is the key to their large-scale application. Therefore, this review aims to introduce the preparation methods of moisture swing sorbents and the key factors affecting their CO₂ adsorption and desorption performance, in order to promote further research and development of moisture swing sorbents.
