The morphology, structure and composition of binary xerogel powders and aerogel powders were characterized by FT-IR, TEM, XRD and nitrogen adsorption.

Single-walled carbon nanotubes were synthesized by catalytic decomposition of a CH4 / H2 mixture at 860~960 ℃ over the Fe2O3 / Al2O3 binary aerogel.

Normally silica aerogels materials have a large affinity to absorb liquids such as water due to their high porosity with pores open" to the surface.

General approach to the surface of the silica aerogels with large amount of hydroxyl, which makes it easy to absorb moisture in the air, water easily broken, the negative of its performance, in addition to supercritical drying process with high energy consumption, high-risk, non-consecutive affect the production characteristics of the widespread use of silica aerogels.

The results show that the physical and hydrophobic properties of the silica aerogels depend on the volume ratio to TMCS ot hexane.

This study aims to study the properties of silica aerogel composites and heat transfer simulation.

The thermal decomposition of silica aerogel modified by methyl groups in air is investigated by Fourier transform infrared spectroscopy(FTIR) and thermogravimetry(TG)-differential thermogravimetry(DTG).
