Incorporation of Lithium into TiO2 Host and its Application in Photocatalysis

Abstract

In this work we prepared the stable photocatalyst by the incorporation of lithium into TiO₂ host. Lithium hydroxide was used as the modifier. Titanium host material was in two forms: commercial titanium dioxide (anatase. Police Chemical Factory, Poland) and titanium slurry that was slightly crystallized. The prepared materials have been characterized by XRD. FTIR and UV-Vis/DR methods. The XRD analysis showed that the main component of these samples was lithium titanate—Li₂TiO₃. The photocatalytic activity of prepared materials was tested in the photocatalytic reactions of oil and phenol decomposition in water. It was found that both oil and phenol undergo the photocatalytic decomposition over lithium-TiO₂ and the activity of these materials was higher in comparison with that of pure anatase host.
