The Ti(C, N, O) nanoparticles have been prepared by using binary carbonaceous titania aerogel as precursor of carbothermal reduction reaction. The binary aerogel precursor, composed of binary carbon-titania nanoparticles with particle sizes in the range 1-8 nm, is obtained by a sol-gel supercritical fluid drying method. This method provides a homogeneous distribution of titania within carbon and high...
A novel synthesis process, based on a carbothermal reduction reaction of binary carbonaceous silica aerogels, has been developed for producing nanometre silicon carbide whiskers. The process uses binary carbonaceous silica aerogels as precursors. The precursors, which are derived from carbonaceous sol and silica sol, are prepared by sol-gel supercritical fluid drying and provide a high contact area...
The activities of activated carbon fibers (ACFs) from ethylene tar pitch and cellulose with various surface areas were examined for the oxidative conversion of SO 2 into aq.H 2 SO 4 in the presence of H 2 O and O 2 , and compared to those of coal tar pitch and polyacrylonitrile based ACFs. Cellulose ACF with surface area of ∼1000 m 2 /g after calcination...
