Metal/oxide composite aerogels can be used as catalysts because of their high specific surface area.

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).

CuO(CoO,MnO)/SiO2 composite aerogels with transition metal oxides as high as 75%(in mass) were prepared by using tetraethyl orthosilicate(TEOS) and acetate of Cu,Co and Mn via the sol-gel process and ambient pressure drying technique,and the gelatination mechanism was investigated.

Presently,silica aerogels are the lightest solid material which have the best property in thermal insulation and have the higher porosity,the lower sound velocities in the world.

The structure and properties of the doped silica aerogels and the pure silica aerogels prepared with the same method were studied by SEM and BET.

The thermal conductivity of silica aerogels doped with TiO 2 powder and ceramic fibers was investigated by varying the gas pressure and the temperature.

Hydrophobic silica aerogels were prepared from cheap waterglass precursors via surface modification of wet gels and ambient pressure drying route.

Preparation and characterization of CuO(CoO,MnO)/SiO_2 nanocomposite aerogels as catalysts carrier by sol-gel process

Cu-rich Cu/SiO_2 nanocomposite aerogels ,in which mass fraction of Cu could reach as high as 66%, were firstly prepared by sol-gel process of Cu-containing tetraethyl orthosilicate (CuTEOS).

CuO(CoO,MnO)/SiO2 nanocomposite aerogels with transition metal-oxides as high as 75wt% were prepared from tetraethyl orthosilicate(TEOS) and acetate of Cu,Co and Mn via sol-gel process and ambient pressure drying technique.
