Photocatalyst is an environmental clean-up material when exposed to light. It can decompose organic compounds, bacteria and fungi as well as foul odors. Titanium dioxide (TiO2) has long been well known for its powerful photocatalytic activity. However, its properties depend on several factors and synthesis method is one of them. In this work, TiO2powders were prepared by three methods, namely microwave-assisted hydrolysis of titanium oxysulfate (TiOSO4), hydrolysis of TiOSO4, and also by calcining of TiOSO4. Photocatalytic activity of the obtained TiO2powders were evaluated through the decomposition of methylene blue in comparison with P25 (Degussa). Results showed that the TiO2prepared at conditions of microwave 100 watts, irradiation time of 10 min was most effective when compared with the others in this work.

[Bmim]PF6ionic liquid was synthesized through two-step reaction in the unmodified microwave oven and ionic liquid synthesis conditions were optimized, the influence factors of microwave-assisted synthesis ionic liquid was discussed. Titanium dioxide photo-catalysts using [Bmim]PF6ionic liquid as medium were prepared. Result indicated that the nanoparticle titanium dioxide obtained in [Bmim]PF6by microwave radiation exhibited higher photocatalytic activity than that by traditional methods, with the degradation ratio of phenol of 99.23% within 16 h.
