Nickel doped Titanium dioxide phase B nanowires (Ni/TiO2(B) NWs) were successfully fabricated by a hydrothermal method and characterized by XRD, FE-SEM, UV-vis and XPS spectroscopy. The FE-SEM images of the surface morphology showed that the size of nickel doped TiO2(B) phase crystal was small (19 – 29 nm). The results indicated that the uniform Ni doped TiO2(B) nanowires with a length of about 5 µm and an average diameter of about ∼204.80 nm were produced. The result also showed composite with 4 mol% Ni doped TiO2(B) NWs phase exhibited optimum photocatalytic activity for the synergeric effects of electrical conductivity and band gap energy. The properties study of Ni/TiO2(B) NWs leading to a new applications of high-performance materials as solar cells, electronics batteries and many other applications.
