Abstract

A technique is introduced to strongly ­reduce Pt use for photocatalytic hydrogen generation from TiO2 nanotubes. By site selectively depositing thin layers of Pt only at the “mouth” of the nanotubes, and with a subsequent thermal de­wetting step, an outstanding photocatalytic ­improvement with minimal amounts of cocatalyst is achieved.
