Abstract
An electrical resistive device, including: an array of titania nanotubes open at an outwardly-directed end formed by anodizing at least a portion of a titanium layer; a plurality of palladium (or other noble metal) clusters having been deposited atop the nanotube array; and the nanotube array mechanically supported by an integral support member. The array of titania nanotubes may include a dopant. An exposure of titania nanotube array to radiant energy emitted within a range of frequencies from visible to ultraviolet, in the presence of oxygen, removes a contaminant, if present. The titanium layer may be deposited atop the integral support; or the unique doped titanium layer can be produced, prior to the anodizing thereof, by depositing titanium along with dopant atop the integral support member by a co-deposition process. Also, supported: method(s) of producing the electrical resistive devices.
