摘要
Crystalline TiO2 nanoparticles were synthesized by hydrolysis of titanium tetrabutoxide in the presence of hydrochloric acid in NP-5 (Igepal CO-520)/ cyclohexane reverse micelle solution at room temperature. Pure rutile nanoparticles were obtained at an appropriate acid concentration. The influences 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 the TiO2 particles were investigated.
