The water-in-oil (W/O) miniemulsion system was used to prepare nano-TiO2 particles. The nano-TiO2 particles were characterized by XRD, FTIR, DRS, SEM and BET surface area analysis. The photoactivity of nano-TiO2 particles was evaluated by photocatalytic degradation of methyl orange. The results show that nano-TiO2 particles, prepared by miniemulsion, have a higher efficiency in decomposition of methyl orange than P25 and TiO2 synthesized via the sol-gel method due to the high surface area and optimum phase constitution.
