摘要
Small titanate nanowires with NaTi2O4（OH） formulation were directly synthesized via the hydrothermal reaction of amorphous titanate particles with concentrated Na OH solution.The average width of these nanowires is smaller than 20 nm,and the surface area is higher than 200 m-2/g.Compared with the larger nanowires obtained by the hydrothermal treatment of crystalline titania in alkaline solution,these small nanowires exhibit larger adsorption capacities and faster adsorption rate in the removal of both heavy metal ions and dyes.
