PdO nanoparticles grown on the surface of nanostructured WO3 photoanodes dramatically increase the faradaic efficiency of water oxidation from 52% to 92%, whilst also enhancing photocurrent generation and electron extraction rates.
Unique nanorods/nanoparticles/nanoflakes WO3 triple-layers acting as efficient photoanodes are grown on a metallic W foil by a simple one-step anodization method.
