Enhancing Visible Light Photocatalysis by N-doping

Barakat MA1-

This article describes the role of N-doping with TiO2 nanoparticles in enhancing visible light photo catalysis. Anion doping with nitrogen ions plays an important role in enhancing effectiveness of TiO2 by introducing trapping sites. Thus, doped nanostructured TiO2-xNx films have been synthesized, characterized, and investigated as visible light photo catalysts for the degradation of pollutants in water. The synthesized nanoparticles can be investigated by suitable technique such as Raman and/or IR spectra in order to make evidence of the fixed amount of nitrogen. Photo degradation of chloro-phenols, as a model for hazardous pollutants, has been studied.
