Abstract

Synthesis of nanometer-sized mesoporous oxide spheres was reported. The synthesized oxides were silica and alumina. The synthesis was performed in the presence some organic solvent with aqueous ammonia as catalyst to control hydrolysis of tetraethyl orthosilicate (TEOS) and aluminum tri-sec-butoxide. Thermo gravimetric analysis showed that block copolymer templates can be removed between 150 and 350 °C.
