Development of modified N doped TiO2 photocatalyst with metals, nonmetals and metal oxides

This paper presents a critical review of novel achievements in the modification of N-TiO2 photocatalytic systems aimed at enhancing TiO2 applications in the areas of energy conversion and environmental clean-up. Herein we studied the synthesis, physical properties, as well as synergism of modified N-doped TiO2. Based on the studies reported in the literature, metal, nonmetal and metal oxide modified N-TiO2 are very effective systems to extend the activating spectra to the visible range. Therefore, modified N-TiO2 play an important role in the development of efficient photocatalysts for future perspectives.
