Boron and nitrogen codoped TiO{sub 2} nanorods (BNTRs) were synthesized via two-step hydrothermal reactions using TiN as a starting material. The as-prepared samples were characterized by X-ray diffraction, field-emission scanning electron microscope (SEM), transmission electron microscopy and X-ray photoelectron spectroscopy techniques. The results showed that TiO{sub 2} nanorods with the diameter of approximately 50-100 nm and the length of several micrometers were doped by the interstitial N and B. The nanorods were firstly formed in the hydrothermal synthesis of nitrogen doped TiO{sub 2}. The growing process of nanorods was observed by SEM and a most probable formation mechanism of the trititanate nanorods was proposed. The BNTRs showed a higher photocatalytic activity and a bigger photocurrent response than N-TiO{sub 2} nanorods under visible light irradiation. - Graphical abstract: Boron and nitrogen codoped TiO{sub 2} nanorods (BNTRs) were synthesized using TiN. The BNTRs showed a higher photocatalytic activity and a bigger photocurrent than N-TiO{sub 2} nanorods (NTRs) under visible light irradiation. Highlights: > Novel B- and N-codoped TiO{sub 2} nanorods (BNTRs) are designed and synthesized. > A most probable formation mechanism of the trititanate nanorods is proposed. > The BNTRs show an outstanding photocurrent response under visible light. > The BNTRs exhibit an improved visible light photocatalytic activity.
