Abstract: In this study a simple method of preparation of UV-vis light-active TiO₂ photocatalysts is presented. The new photocatalysts were obtained by thermal modification of the anatase TiO₂ powder (Police, Poland) with cyclohexane. The obtained materials were investigated by means of UV-vis/DR, FTIR/DRS, XRD. BET specific surface area and carbon content was also measured. Furthermore, photocatalytic activity of the new photocatalysts were investigated under UV-vis irradiation with high UV light intensity during of phenol degradation. TiO₂/C photocatalysts show higher photocatalytic activity in comparison with TiO₂-starting and commercial KRONOClean 7000, regardless of calcination temperature. It was found that the smaller amount of carbon in TiO₂/C photocatalyst sample the better photocatalytic activity of tested nanomaterials.
