Crystalline TiO₂ nanoparticles were synthesized by hydrolysis of titanium tetrabutoxidein the presence of hydrochloric aeid in NP-5 (lgepal CO-520)/ cyclohcxane reverse micellesolution at room temperature. Pure rutilc nanoparticles were obtained at an appropriate acidconcentration. The influcnces of various reaction conditions such as the concentration of acids,water content value (w=[H₂O]/[NP-5]) on the formation, crystal phase, morphology, and size of theTiO₂particles were investigated.
