title: Light-driven hydrogen production from aqueous solutions based on a new Dubois-type nickel catalyst.
abstract: 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 H2generation [Ni(P2RN2R')2(BF4)2]4-, R = Ph, R' = [PhSO3]-(NiS). This noble metal free hybrid exhibits remarkable catalytic activity with a turnover number of 511 for H2production and a photon-to-H2conversion efficiency of 12.5%. The mechanistic insight into such high efficiency in this photocatalytic system was examined using a combination of steady-state emission and time-resolved absorption spectroscopy.
