A simple [FeFe]‐hydrogenase mimic, Fe 2 S 2 (CO) 6 , was integrated with CdSe quantum dots to form a sensitized electrode on a p ‐NiO layer, which can start to catalyze proton reduction at a bias voltage as positive as ≈0.3 V (vs. NHE) in neutral water. The result provides a promising way to overcome the much more negative onset bias of [FeFe]‐hydrogenase mimics for H 2 evolution under mild conditions.
