Abstract

Climate change resulting from excessive greenhouse gas emissions is a significant global issue, with carbon dioxide (CO₂) being the largest contributor to anthropogenic climate change. This research proposes the development of amine-functionalized nanocellulose aerogels sourced from biomass waste for efficient CO₂ capture. Nanocellulose is a sustainable polymer that offers renewability, high surface area, biodegradability, and minimal environmental footprint. The addition of amine groups is anticipated to enhance CO₂ adsorption through strong chemisorption, while the highly porous aerogel network facilitates gas diffusion and enhances adsorption capacity. This study aims to valorize low-value biomass waste into biodegradable high-performance CO₂ adsorbents, offering a dual benefit for climate change mitigation and renewable biomass energy transition adhering to the principles of negative carbon solution.
