Abstract
An array of transition metal tubular architectures, where the transition metal tubular architectures are comprised of a transition metal oxide, sulfide, or selenide, and wherein transition metal tubular architectures are less than 100 nm in length. The transition metal tubular architectures can be at least partially crystalline. Within the array of transition metal tubular architectures, at least 80% of the transition metal tubular architectures can be less than 100 nm in length.

1-17. (canceled)
A method of making an array of transition metal tubular architectures, the method comprising:
- oxidizing a transition metal that is immersed in a fluid medium that comprises an electrolyte, an acid, and a polymer for a time and under conditions sufficient to oxidize the transition metal and produce the array of transition metal tubular architectures that are less than 100 nm in length.
The method of claim 30, wherein the transition metal tubular architectures are characterized by diffraction peaks at 25.3°, 37.7°, 47.8°, 53.8°, and 54.9° (2θ) in XRD pattern analysis, corresponding to the (101), (004), (200), (105), and (211) facets.
A method for splitting water comprising:
- contacting water with light and with an array of transition metal architectures that comprise nanotubes comprising titanium oxide, titanium sulfide, or titanium selenide, wherein transition metal tubular architectures are less than 100 nm in length.
A device comprising array of transition metal tubular architectures that are less than 100 nm in length, wherein said array comprises an oxidized transition metal that is an oxide, sulfide, or selenide of at least one transition metal.
