Nanoparticles of tin oxide (SnO 2 ) have been prepared from water-in-oil microemulsions consisting of water, AOT (surfactant), and n-heptane (oil). Precursor hydroxides were precipitated in the aqueous cores of water-in-oil microemulsions and then calcined at 600Β°C for 2 h to form tin oxide powder.
The effect of surfactant type and temperature on the kinetics of the formation of platinum nanoparticles in water-in-oil microemulsions by chemical reduction of PtCl 2- 6 were examined with timeresolved UV-vis absorption spectroscopy. The surfactants used were poly(ethylene glycol)monododecyl ethers
Submicron spherical particles of colloidal silica were prepared by the hydrolysis of sodium silicate in a Triton X-100-hexanot-cyclohexane-water microemulsion system . The average diameter of the silica particles obtained was about 30 not The formation of a microemulsion by using a cyclohexane solut
