Patent ID: 7867437

Claim:
A method of manufacturing Ni-doped TiO 2 nanotube-shaped powder, the method comprising the steps of: forming Ni-doped TiO 2 nanotube-shaped powder using Ni-doped TiO 2 powder as a starting material; and drying the Ni-doped TiO 2 nanotube-shaped powder at 60 to 200° C. for 2 to 24 hours, wherein the step of forming Ni-doped TiO 2 nanotube-shaped powder comprises the steps of: adding the Ni-doped TiO 2 powder to a NaOH solution; heat treating the NaOH mixture in an autoclave at 120 to 180° C. for 24 to 72 hours; washing the resultant with an HCl solution and distilled water; and collecting Ni-doped TiO 2 nanotube-shaped powder.
