Lithium ion intercalation of 3-D vertical hierarchical TiO2 nanotubes on a titanium mesh for efficient photoelectrochemical water splitting.

In this communication, we report for the first time the demonstration of a lithium ion intercalation strategy to significantly enhance the photoelectrochemical water splitting performance on 3-dimensional vertical hierarchical top-porous-bottom-tubular TiO₂ nanotubes on a fabricable titanium mesh.
