摘要：
In this work, we report a new photocatalytic system that links multifunctional semiconductor nanocrystals with emerging water-soluble molecular catalysts made of earth-abundant elements for H-2 generation [Ni((P2N2R)-N-R')(2)(BF4)(2)](4-), R = Ph, R' = [PhSO3](-) (NiS). This noble metal free hybrid exhibits remarkable catalytic activitywith a turnover number of 511 for H-2 production and a photon-to-H-2 conversion efficiency of 12.5%. The mechanistic insight into such high efficiency in this photocatalytic system was examined using a combination of steadystate emission and time-resolved absorption spectroscopy.
