In this contribution, we report an efficient homogeneous system for the visible light-driven H-2 production from aqueous protons. This comprises a macrocyclic phthalycyanine cobalt complex [(CoPc)-Pc-II(-2)] as a hydrogen-evolving catalyst (HEC), [Ru-II(bpy)(3)]Cl-2 (bpy = 2,2'-bipyridine) as a photosensitizer (PS) and triethylamine (TEA) as a sacrificial electron donor (SED). The system gives up to 2400 TON versus the catalyst with an initial TOF as high as 680 TON h(-1). Phthalocyanine cobalt and its derivatives are a promising new direction for molecular catalysts readily accessible in a large scale and low-cost achieving the photogeneration of H-2.
