Abstract

Nanocrystalline γ-Al₂O₃ and FeCo-Al ₂O₃ nanocomposites containing FeCo alloy nanoparticles well dispersed in the nanocrystalline γ-Al₂O₃ matrix were successfully obtained by the sol-gel method using aluminum tri-sec-butoxide and iron and cobalt nitrates as precursors. The gels were submitted to high temperature supercritical drying which allowed to obtain aerogels with high surface areas and pore volumes.
