Prepararion of Ni/SiO_2 Composite Aerogel by Sol-Gel Process of Ni-containing Tetraethyl Orthosilicate

Ni-rich Ni/SiO2 composite aerogels in which weight percentage of Ni could reach 60% werefirstly prepared by sol-gel process of Ni-containing tetraethyl orthosilicate (NiTEOS). The influenceof H2O, catalyst, solvent and compostcomposition of Ni-containing tetraethyl orthosilicate on the sol-gelprocess was discussed. The specific sufrace areas of Ni/SiO2 composite aerogels are in the rangeof 420~650m2/g.
