Research highlights: {yields} The formation of N, F-codoped TiO{sub 2} nanorod arrays via the LPD. {yields} Calcination temperature greatly effects the incorporation of N and F into TiO{sub 2}. {yields} TNRAs calcined at 450 {sup o}C showed highest visible light photocatalytic activity. {yields} A synergetic effect of 1D nanorod arrays and appropriate amount of N and F codoping. -- Abstract: An efficient method for the preparation of N-F-codoped visible light active TiO{sub 2} nanorod arrays is reported. In the process, simultaneous nitrogen and fluorine doped TiO{sub 2} nanorod arrays on the glass substrates were achieved by liquid phase deposition method using ZnO nanorod arrays as templates with different calcination temperature. The as-prepared samples were characterized by Raman spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and UV-vis absorption spectra measurements. It was found that calcination temperature is an important factor influencing the microstructure and the amount of N and F in TiO{sub 2} nanorod arrays samples. The visible light photocatalytic properties were investigated using methylene blue (MB) dye as a model system. The results showed that N-F-codoped TiO{sub 2} nanorod arrays sample calcined at 450 {sup o}C demonstrated the best visible light activity in all samples, much higher than that of TiO{sub 2} nanoparticles and P25 particles films.
