The structural properties of CoFe2O4-SiO2 highly porous nanocomposite aerogels have been investigated by X-ray Absorption Spectroscopy and Transmission Electron Microscopy techniques. The aerogels are obtained by supercritical drying of composite gels obtained using a two step procedure where fast gelation is achieved using urea in the second step. The formation of CoFe2O4 nanocrystals in the silica matrix begins after calcination at 750 degrees C of the parent aerogel and is complete after calcination at 900 degrees C, while the high porosity of the sample is mostly retained.
