A Hybrid Photocatalytic System Comprising ZnS as Light Harvester and an [Fe2S2] Hydrogenase Mimic as Hydrogen Evolution Catalyst

Photo opportunity: A highly efficient and stable hybrid artificial photosynthetic H2 evolution system is assembled by using a semiconductor (ZnS) as light-harvester and an [Fe2S2] hydrogenase mimic ([(μ-SPh-4-NH2)2Fe2(CO)6]) as catalyst for H2 evolution. Photocatalytic H2 production is achieved with more than 2607 turnovers (based on [Fe2S2]) and an initial turnover frequency of 100 h−1 through the efficient transfer of photogenerated electrons from ZnS to the [Fe2S2] complex.
