Amine grafted cellulose aerogel for CO2 capture
A cellulose aerogel (CA) was fabricated by a phase inversion induced sol-gel process along with supercritical drying. An amine grafted cellulose aerogel (AGCA) was prepared by grafting 3-aminopropyltriethoxysi...

Facile synthesis of monolithic carbon/alumina composite aerogels with high compressive strength using different inorganic aluminium salts
Resorcinol–formaldehyde/alumina composite (RF/Al2O3) gels were initially prepared using sol–gel techniques, and then dried to aerogels with supercritical fluid CO2. RF/Al2O3 aerogels were successfully converted t...
