Abstract : Photocatalytic titanium dioxide (TiO2) nanoparticles were synthesized via acid assisted sol-gel process. The
effects of different acids namely; acetic acid, hydrochloric acid, and nitric acid on the formation of TiO2 nanoparticles and
their photocatalytic properties were investigated. XRD, SEM, and UV-Vis spectrophotometer analyses were performed to
examine the physical and chemical characteristics of the nano powders. The results showed that only anatase phase of
TiO2nanoparticleswith different crystallite size and morphology weresynthesized with respect tothe kinds of acid and the
procedure applied. The TiO2 powder synthesized from HCl exhibited highest photocatalytic activity, and its methylene blue
photodegradation efficiency was 98.1% in 90 minUV irradiation.
