Specific nanocatalyst placements improve visible-light water splitting

Utilizing the anisotropy of nanorods to separately anchor hydrogen reduction and water oxidation co-catalysts could provide the key to efficient water splitting

Photoexcitation of a CdS nanorod (yellow) provides the driving force for transfer of holes to the molecular catalyst (structure on top). Meanwhile, the CdS nanorod acts as a conduit to shuttle electrons to the hydrogen-evolving Pt nanoparticle (grey) affixed to the nanorod tip, completing the reaction without sacrificial agents.
