A simple preparation of nitrogen doped titanium dioxide nanocrystals with exposed (001) facets with high visible light activity

Nanoscaled nitrogen doped anatase TiO(2) with dominant (001) facets, which exhibited high photocatalytic activity and excellent photoelectrochemical properties under visible light irradiation, was successfully synthesized by solvothermal treatment of TiN in acidic NaBF(4) solution for the first time.
