Abstract

Bio-inspired noble-metal-free supramolecular systems were constructed by host-guest inclusions of an FeFe-hydrogenase mimic and an organic dye into cyclodextrins respectively, which give typically a ninefold increase in the TON, a sixteenfold enhancement in the quantum efficiency, and a threefold extension in lifetime as compared to the same system in the absence of cyclodextrin for photocatalytic H₂ production in aqueous solution.
