Room temperature synthesis of titanium dioxide nanoparticles of different phases in water in oil microemulsion

摘要

Work up to now on titanium dioxide nanoparticle synthesis using water in oil microemulsion has focused extensively on using a two-microemulsion method, in which mixing of two microemulsions with two reactants dissolved in the aqueous core of the microemulsion leads to formation of titanium dioxide nanoparticles by intermicellar exchange. The nanoparticles produced are amorphous and convert to anatase on heating at 600-750°C and to rutile above 900°C.
