Abstract:Excessive emission of CO₂ in the air has posed a great threat to human health and the environment. Therefore， the development of green and sustainable air filters with high efficiency has become a focus. Nanocellulose-based aerogels are widely used in the manufacture of air filters due to their high specific surface area， high reactivity， and high plasticity. In this paper， the preparation methods of nanocellulose-based aerogels were expounded， the advantages and disadvantages of each method were evaluated， the current research status and progress of nanocellulose-based aerogels in CO₂ absorption were summarized， and the future development trends and challenges of nanocellulose-based aerogels were prospected.
