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

Abstract

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.
