In this study, titanium nitride nanotubes(TiN NTs) film is directly prepared on a Ti substrate through anodic oxidation process and subsequent nitridation in ammonia atmosphere.The prepared TiN NTs film is proposed as a novel catalyst towards V(Ⅱ)/V(Ⅲ) redox couple for the negative electrode in a static vanadium redox battery.Scanning electron microscopy(SEM) results confirm that TiN NTs retain its parental morphology of TiO_2 NTs.X-ray diffraction(XRD) pattern show that Ti O2 is transformed into TiN and Ti...
