A robust, inexpensive, and efficient photocatalytic system consisting of an artificial water‐soluble [FeFe]‐H 2 ase mimic 1 , CdTe quantum dots, and ascorbic acid (H 2 A), for H 2 production in pure water at room temperature has been developed. With this system, 786 μmol (17.6 mL) H 2 were obtained after 10 h irradiation ( λ >400 nm) with TON up to 505 and TOF up to 50 h −1 under optimized conditions.
