Nitrogen-doped graphene-TiO _x N _y nanocomposite electrode for highly efficient capacitive deionization.

ABSTRACT: In this work, the first-ever reported nanocomposite electrode of nitrogen-doped graphene-titanium oxynitride (NG-TiO _x N _y ) for capacitive deionization (CDI) was synthesized via hydrothermal reaction and a high-temperature nitridation process. The physiochemical characterizations revealed that the nitrogen was doped in the graphene structure mainly in the form of graphitic nitrogen and the TiO _x N _y was successfully formed via TiO₂ nitridation process. The layered NG nanosheets facilitated the diffusion of ions in saline water and formed electrical double layer on the surface of the electrode material, while the presence of TiO _x N _y enhanced the electrochem
