With a view to realizing a titanium oxide structure that has a large surface area and enables efficient transfer of ions and electrons by virtue of 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 composition and a process for producing the composition; and a photoelectric conversion element comprising the titanium oxide structure or porous titanium oxide composition.

Titanium oxide structure and porous titanium oxide composition

Straight, nano-scale-order amorphous carbon tubes having a long-term stable ability for storing various kinds of gases and being stable in shape, and a novel process for producing said carbon tubes with high purity, high yield and high mass-productivity are provided. The amorphous nano-scale carbon tubes are prepared by subjecting a heat-decomposable resin having a decomposition temperature of 200 to 900&#xb0; C. to an excitation treatment in the presence of a metal powder and/or a metal salt, or by subjecting a carbon material containing &#x2014;C&#x2261;C&#x2014; and/or &#x2550;C&#x2550; to a heat-treatment at 3000&#xb0; C. or lower.

Amorphous nano-scale carbon tube and production method therefor

Disclosed are an iron-carbon composite in which 10 to 90% of the internal space of a nanoflake carbon tube or a nested multi-walled carbon nanotube is filled with iron carbide or iron; a carbonaceous material containing such iron-carbon composites; and a process for preparing the same. The iron-carbon composite is useful for electron emitting materials and other applications.
