  • Method of manufacture Ni-doped TiOnanotube-shaped powder and sheet film comprising the same
    Patent number: 7867437
    Abstract: The present invention provides a method of manufacturing Ni-doped TiO2 nanotube-shaped powder and a method of manufacturing a sheet film to be inserted into a high-pressure hydrogen tank for a fuel cell vehicle by mixing the Ni-doped TiO2 nanotube-shaped powder with a binder and compressing the mixture. The method of manufacturing Ni-doped TiO2 nanotube-shaped powder includes: forming Ni-doped TiO2 nanotube-shaped powder using Ni-doped TiO2 powder as a starting material; and drying the Ni-doped TiO2 nanotube-shaped powder in the temperature range of 60 to 200° C. for 2 to 24 hours.
