  • TITANIUM OXIDE-COVERED CARBON FIBER AND POROUS TITANIUM OXIDE-COVERED CARBON MATERIAL COMPOSITION
    Publication number: 20110083737
    Abstract: With a view to realizing a titanium oxide composite that has a large surface area and that enables efficient transfer of electrons by covering a surface of rod-like or fibrous carbon with a covering layer comprising titanium oxide particles connected to one another, an object of the invention is to develop a material useful as an active material for dye-sensitized solar cells, and a process for producing the material; a porous titanium oxide-covered carbon material composition, and a process for producing the composition; and a photoelectric conversion element comprising the titanium oxide-covered carbon material or porous titanium oxide-covered carbon material composition.
