Cellulose aerogels, made from nanofibrils found in plants, have several unique features, one of which is super high oil absorption capacity that is several times higher than commercial sorbents available in the market. Researchers have created wood-based structures for oil/water separation, utilizing the native feature of wood, i.e. its tubular porosity and hierarchical organization. The novelty here is the development of new processing routes for hierarchical wood structures scaled from nano-, micro-, to macroscales.
