Popis:	Transition metal ion of Ni 2+ doped TiO 2 nanostructured powders were synthesized by mechanical alloying to shift the adsorption threshold into the visible light region. The X-ray patterns for samples showed three phases of TiO 2 such as rutile, anatase and brookite. The 8 wt.% Ni-doped TiO 2 powders consisted of spherical primary particles with a size of about 50 nm and secondary particles about 100–300 nm. The transition metal ion of Ni 2+ doped TiO 2 powders showed excellent photo-oxidative ability in 4-chlorophenol degradation.
