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.
