Aromatic nitro compounds were chemoselectively reduced to the corresponding anilines by using TiO2
nanoparticle as photocatalyst under sunlight irradation. This method is highly efficient with excellent yields (>90%)
and wide functional group tolerance such as carbonyl, halogen, amino, cyanide groups. In this study TiO2 nanoparticle
with a bicrystalline (anatase and brookite) framework was synthesized directly under high intensity ultrasound
irradiation without thermal treatment, by the agglomeration of monodispersed TiO2 sol particles. The resulting material
was characterized by XRD, N2 adsoption-desorption and diffuse reflectance spectroscopy.
