Porous polycrystalline NiO nanowires were prepared via thermal decomposition of the nickelous precursor synthesized via the hydrothermal reaction of nickel chloride with trisodium citrate dehydrate (C(6)H(5)Na(3)O(7)a <...2H(2)O) in ethanol-H(2)O binary solution. The porous polycrystalline nanowires with the diameters of 350 to 450 nm were constructed from NiO nanocrsystals with the cubic structure and the sizes of 8 to 12 nm. The photocatalytic activity of the as-prepared porous NiO nanowires for the degradation of acid scarlet dye was studied. It was found that their photocatalytic activity was stronger than that of NiO powders.
