Brookite TiO2 nanoparticles with amphiphilic properties were successfully synthesized with a water-soluble titanium glycolate complex precursor using an oleate-modified hydrothermal growth process. The similar to 20-40 nm TiO2 nanoparticles were highly dispersible in both water and cyclohexane. The activity of the brookite nanoparticles for the degradation of acetaldehyde under UV irradiation was higher than that of Degussa P-25 TiO2 powder. A spin-coated brookite film prepared on a polyimide substrate exhibited photoinduced hydrophilicity. Thus, these synthesized brookite solution. nanoparticles could be applied as a photocatalytic coating
