Metal/ oxide composite aerogels can be used as catalysts because of their high specific surface area. In this paper, Co-rich Co/SiO2 composite aerogels in which mass fraction of Co can reach 66%were firstly prepared by sol - gel process of Co-containing tetraethyl orthosilicate. The influence of H2O, catalyst, solvent and composition of Co-containing tetraethyl orthosilicate on the sol-gel process are discussed.
