Background: Photocatalytic process is performed when the material absorbs energy from the sun, for example, or from an ultraviolet light source that is at least equal to the energy gap. Electrons move from the valence band to the conduction band, so we have an electron in the conduction band and a positive hole in the valence band. The positive hole is a strong oxidizer that can oxidize particles. In this work the TiO2 nanoparticles will be prepared with different concentration of urea in order to get modified TiO2. We will also study the effect of urea modified TiO2 on the photocatalytic process.
