Abstract

Nanocrystalline γ-Al2O3 and FeCo-Al2O3 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.
