TEMPO-oxidized cellulose nanofibril (TOCNF)-based porous structures offer exceptional properties but face structural instability under various conditions. This study introduces a novel approach to improve the stability and adsorption capacity of TOCNF-based aerogels by incorporating chitosan (Ch) and crosslinking with dialdehyde cellulose (DAC). DAC can crosslink with TOCNF through hemiacetal formation and Ch via Schiff base formation, leading to significant improvement structural integrity and pH stability. The resulted aerogels enhanced adsorption capacity for Congo Red and showed excellent reusability for methylene blue adsorption, making them promising materials for various environmental and biomedical applications.
