Özet

Although several semiconducting metal oxides are used in photocatalysis works, it is known that the most attractive photocatalyst that is worked on most is TiO2 (titanium (IV) oxide). The reason for this is that the valence band hole of TiO2 is more positive, cheaper and more resistant to chemical substances when compared to the other semi-conductors. In this study, the effect of ultrasound energy on the photocatalytic activity of TiO2 photocatalyst was examined by giving ultrasound energy to TiO2, which is a photocatalyst, at certain intervals. As a result of the SEM and BET analysis applied to TiO2, it was determined that ultrasound energy increased the surface area of TiO2 photocatalyst and as a result of this, it increased the photocatalytic activity of TiO2 photocatalyst.
