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.
