Water reduction systems that use a bis-cyclometalated IrIII photosensitiser (PS) along with homogeneous Pd complexes as a source of in-situ-formed colloidal Pd as the water reducing complex (WRC) and triethylamine (TEA) as the sacrificial electron donor were tested and characterised with respect to their photocatalytic H2 production performance. It was confirmed that substitution of the 2-(pyridin-2-yl)benzen-1- ide (pyb) ligand in the well-known system [Ir(pyb)2(bpy)]+ (bpy=2,2?-bipyridine) by the fluorinated cyclometalating ligand 5-fluoro-2-(5-methylpyridin-2-yl)benzen-1-ide (Fmpyb) tremendously enhanced the H2 production rate. Moreover, variation of the bidentate N^N ligand bpy by alkyl substitution in the 4,4?-position resulted in an increase in the H2 production yield by a factor of three. The incident-photon-to-hydrogen-efficiency could be enhanced from 2.6 to 12.3 %. Furthermore, a new dinuclear Co complex was used as a reduction catalyst and showed up to 760 turnovers after 20 h. A detailed study of the concentration impact of all components in the photoredox system was performed. DFT calculations were used to aid the explanation of the findings. Teamwork 2.0: A highly active system for photocatalytic water reduction consisting of an Ir photosensitiser and a Pd dichloro complex as the source of catalytically active Pd0 is described. Additionally, the introduction of a hitherto unknown dinuclear Co complex as a water reduction centre resulted in a system with a comparably high initial activity. Copyright

A photocatalytic water-reducing system utilizing a bis-cyclometalated bipyridyl iridium(III) photosensltizer (PS) and a platinum or palladium heterogeneous catalyst was used to Identify systematic property-activity correlations among a library of structural derivatives of [lr(ppy) 2(bpy)]+. A heterogeneous Pd catalyst proved to be more durable than its previously reported Pt-based counterpart, allowing for more reliable photosensitlzer study. The deliberate sterlc and electronic variations of the ppy and bpy moieties resulted in a dramatic decrease of the degradation rates observed with selected photosensltizers when compared to the more substitution-labile [Ir(ppy)2(bpy)]+ parent compound. An Improved photosensitlzer structure with a Pd catalyst in a nonligating solvent exhibited a 150-fold increase in catalyst turnover numbers compared to the system using [lr(ppy)2(bpy)]+ and a Pt catalyst. Furthermore, photocatalytic and photophysical studies at varied temperatures provided information on the rate-limiting step of the photocatalytic process, which is shown to be dependent on both the PS and the Pt or Pd catalytic species.
