摘要：

A robust, inexpensive, and efficient photocatalytic system consisting of an artificial water-soluble [FeFe]-H2ase mimic 1, CdTe quantum dots, and ascorbic acid (H2A), for H2 production in pure water at room temperature has been developed. With this system, 786-μmol (17.6-mL) H2 were obtained after 10-h irradiation (Î>400-nm) with TON up to 505 and TOF up to 50-h-1 under optimized conditions.
