Flexible and Porous Nanocellulose Aerogels with High Loadings of Metal–Organic‐Framework Particles for Separations Applications

Flexible and porous aerogels are obtained by combining functional metal-organic frameworks (MOFs) and structural cellulose nanocrystals via a straightforward water-based sol-gel process, followed by freeze-drying. The aerogels have a hierarchical porous structure with controllable MOF loading up to 50 wt%. These hybrid materials can be used as absorbents for water purification.
