25_01b/2013Photoelectrodes: Vertically Aligned Ta3N5 Nanorod Arrays for Solar-Driven Photoelectrochemical Water Splitting (Adv. Mater. 1/2013)

A highly efficient nanorod photoanode for solar-driven photoelectrochemical (PEC) water splitting is reported by Kazunari Domen and co-workers on page 125. The cover image illustrates vertically aligned semiconductor nanorods grown in situ on a metal substrate. The single crystalline 1D nanostructure with low contact barrier makes them ideal building blocks of PEC cells for efficient solar energy conversion.
