Methods of reducing microbial attachment to a surface are provided, including methods comprising illuminating a surface comprising a substrate and a coating on the substrate with ultraviolet light, wherein the coating comprises anatase titanium dioxide nanoparticles functionalized with silver nanoparticles and is optically transparent to visible light; and exposing the illuminated surface to microbes. The coating exhibits a reduction in microbial attachment as compared to the coating absent the illumination.

Silver and titanium dioxide based optically transparent antimicrobial coatings and related methods

In one aspect of the invention, a dye sensitized solar cell has a counter-electrode including carbon-titania nanocomposite thin films made by forming a carbon-based ink; forming a titania (TiO) solution; blade-coating a mechanical mixture of the carbon-based ink and the titania solution onto a substrate; and annealing the blade-coated substrate at a first temperature for a first period of time to obtain the carbon-based titania nanocomposite thin films. In certain embodiments, the carbon-based titania nanocomposite thin films may include solvent-exfoliated graphene titania (SEG-TiO) nanocomposite thin films, or single walled carbon nanotube titania (SWCNT-TiO) nanocomposite thin films.

Catalysts and related methods for photocatalytic production of HOand thermocatalytic reactant oxidation

In one aspect, a method of making non-covalently bonded carbon-titania nanocomposite thin films includes: forming a carbon-based ink; forming a titania (TiO) solution; blade-coating a mechanical mixture of the carbon-based ink and the titania solution onto a substrate; and annealing the blade-coated substrate at a first temperature for a first period of time to obtain the carbon-based titania nanocomposite thin films. In certain embodiments, the carbon-based titania nanocomposite thin films may include solvent-exfoliated graphene titania (SEG-TiO) nanocomposite thin films, or single walled carbon nanotube titania (SWCNT-TiO) nanocomposite thin films.

The present invention provides titanium dioxide/single-walled carbon nanotube composites (TiO/SWCNTs), articles of manufacture, and methods of making and using such composites. In certain embodiments, the present invention provides membrane filters and ceramic articles that are coated with TiO/SWCNT composite material. In other embodiments, the present invention provides methods of using TiO/SWCNT composite material to purify a sample, such as a water or air sample.

Titanium dioxide, single-walled carbon nanotube composites

A mixed anatase-rutile phase, non-stoichiometric titania photocatalyst material is a highly reactive and is a UV and visible light responsive photocastalyst in the as-deposited condition (i.e. without the need for a subsequent thermal treatment). The mixed phase, non-stoichiometric titania thin film material is non-stoichiometric in terms of its oxygen content such that the thin film material shows a marked red-shift in photoresponse.
