RESUMO
Herein, we report a facile route for the synthesis of foam-like porous oxides using carbon spheres and polyvinylpyrrolidone (PVP) as sacrificial templates. The as-prepared porous structures were characterized by XRD, FESEM, TEM and BET methods. These foam-like macroporous oxides are formed through the fusion of oxide nanoparticles around the gas bubbles liberated during the combustion of composites and show good BET surface areas.
