| Summary: | This article presents an overview of the reports on the doping of TiO<sub>2</sub> with carbon, nitrogen, and sulfur, including single, co-, and tri-doping. A comparison of the properties of the photocatalysts synthesized from various precursors of TiO<sub>2</sub> and C, N, or S dopants is summarized. Selected methods of synthesis of the non-metal doped TiO<sub>2</sub> are also described. Furthermore, the influence of the preparation conditions on the doping mode (interstitial or substitutional) with reference to various types of the modified TiO<sub>2</sub> is summarized. The mechanisms of photocatalysis for the different modes of the non-metal doping are also discussed. Moreover, selected applications of the non-metal doped TiO<sub>2</sub> photocatalysts are shown, including the removal of organic compounds from water/wastewater, air purification, production of hydrogen, lithium storage, inactivation of bacteria, or carbon dioxide reduction.
