Abstract
Fe oxide and composite Ti-Fe oxide ultrafine particles have been prepared using sodium bis(2-ethylhexyl) sulfosuccinate (Aerosol OT; AOT)/isooctane reverse micellar solutions. Fe 2 O 3 particles were prepared by mixing a micellar solution containing sulfuric acid solution of ammonium iron(III) sulfate with an alkaline or a neutral micellar solution containing NaOH solution or distilled water, respectively. The formation of TiO 2 particles by adding titanium tetrabutoxide (TTB) to a micellar solution was also facilitated by NaOH. Simultaneous feeding of both TTB and Fe 3+ solutions did not form composite particles but only Fe 2 O 3 particles, indicating that the presence of Fe 3+ prevented the formation of cores of TiO 2 . The TiO 2 particles were thus prepared at first in the micellar solution, to which Fe 3+ -containing micellar solution was fed. The resulting particles possibly have a structure in which TiO 2 particles are coated by Fe 2 O 3 thin layer.
