ABSTRACT
Abstract Flower-like shaped rutile-rich TiO 2 nanoparticles were synthesized by the reaction of HCl with titanium diisopropoxide bis(acetylacetonate) immobilized in reverse micelles composed of oleic acid, water, and xylene. Brunauer Emmett Teller (BET) analysis showed large surface area of the synthesized TiO 2 nanoparticles of 177.8 m 2 /g. We investigated the effect of the concentration of Ti precursor and role of oleic acid in the formation of TiO 2 nanoparticles. Rutile-rich TiO 2 nanoparticles with large surface area showed better photocatalytic activity in decomposing methyl orange under visible-light irradiation than anatase and rutile mixed phase TiO 2 particles.
