Synthesis of Monolithic Fe₂O₃-Al₂O₃Composite Aerogels via Organic Solvent Sublimation Drying

Abstract

Monolithic Fe 2 O 3 -Al 2 O 3 composite aerogels have been prepared successfully via organic solvent sublimation drying method. The results show that a new phase forms when the right amount of ferric oxide is added to the alumina aerogel. From the TEM pictures we can see a shuttle-type structure with the length of about 15 nm forms, which leads to the high surface areas of composited aerogel.
