US Patent 7521394 - TiO nanofiber

US Patent 7521394

Titanium oxide is useful to create white pigments, as a photocatalyst, or in photovoltaic energy conversion. Forming nanostructures for TiO can enhance the utility of the material by providing more reactive surface area. This patent from the University of Illinois teaches a method of making a new TiO nanostructure capable of producing larger quantities at lower cost. Claim 1 reads:

1. A nanofiber, comprising: anatase titanium oxide, where the nanofiber has a longest dimension of at least 2 micrometers, and an aspect ratio greater than 20:1.
