摘要：
A macrocyclic N-heterocyclic carbene (NHC)-cobalt complex was found to act as an improved H-2-evolving catalyst in a [Ru(bpy)(3)](2+)-sensitized photosystem using methylviologen as a redox acceptor (MV2+ + e(-) -> MV+center dot, MV2+ = N,N'-dimethyl-4,4'-bipyridinium), which provides a driving force of only 150 meV for H-2 evolution at pH 5.0.
