Self-Organized Plasmonic Nanowire Arrays Coated with Ultrathin TiO Films for Photoelectrochemical Energy Storage.

The strategic field of renewable energy production and storage requires novel nanoscale platforms that can feature competitive solar energy conversion properties. Photochemical reactions that promote energy storage, such as water splitting and oxygen-hydrogen evolution reactions, play a crucial role in this context. Here, we demonstrate a novel photoelectrochemical device based on large-area (cm) self-organized Au nanowire (NW) arrays, uniformly coated with ultrathin TiO films.
