摘要:A process and apparatus for the synthesis of metal oxide nanopowder from a metal compound vapour is presented. In particular a process and apparatus for the synthesis of TiO 2 nanopowder from TiCl 4 is disclosed. The metal compound vapour is reacted with an oxidizing gas in electrically induced RF frequency plasma thus forming a metal oxide vapour. The metal oxide vapour is rapidly cooled using a highly turbulent gas quench zone which quickly halts the particle growth process, yielding a substantial reduction in the size of metal oxide particles formed compared with known processes. The metal compound vapour can also react with a doping agent to create a doped metal oxide nanopowder. Additionally, a process and apparatus for the inline synthesis of a coated metal oxide is disclosed wherein the metal oxide particles are coated with a surface agent after being cooled in a highly turbulent gas quench zone.

摘要:A method is disclosed for synthesizing nanofilters for water treatment. The method includes: dispersing an active binding agent in an organic solvent solution to create a suspension of the active binding agent and the solution of the solvent; dissolving an organic polymer resin and an anionic surfactant in the suspension of the active binding agent and the solvent solution to create a sol gel; and electrospinning the sol gel to form electrospun nanofiber composites with embedded, surface-active nanoparticles.
