  • In order to effectively utilize visible light in the photocatalytic reaction, nanaocomposite of Ni doped $TiO_2$ and $NiTiO_3$ powders were synthesized by mechanical alloying and heat treatment. About 5.4 wt% of $NiTiO_3$ with particle size less than 15nm was uniformly formed in the Ni-doped rutile $TiO_2$ matrix. The UV/VIS-DRS and PL investigation showed that the nanocompasite $TiO_2$ powders had a longer absorpt ion wavelength (600$\sim$650nm, 2.0$\sim$1.9eV) than that of Ni-doped $TiO_2$ or rutile $TiO_2$ powder. The carbon decomposition of 4-CP by the nanocompasite $TiO_2$ powders were higher than other $TiO_2$ (P-25).
