Titanium dioxide-based photocatalysts, active in the visible light, were synthesized by the sol-gel method using alkoxide titanium precursor. Organic and inorganic compounds were used as dopants for catalysts preparation. The elemental analysis, X-ray diffraction and diffuse reflectance spectroscopy were used to characterize the catalysts. The photocatalytic activity of the synthesized powders was estimated by measuring the decomposition rate of phenol under the visible light (λ>400 nm) in an aqueous solution. The catalysts modified with thioacetamide were found to be the most photoactive.
