Cobalt(II) glyoxime and heterocycle complexes [Co(LL)2pyCl]n+ (LL – α-dioxime, 8-quinolinols, α-diketone dihydrazides, bipyridines, phenanthrolines, pyridyltetrazoles, etc.; n = 0-2) were generated in situ and screened for cocatalytic activity in Eosin Y-catalyzed photoreduction of water in the presence of triethylamine as sacrificial reductant. Noble-metal photosensitizers and water reduction co-catalysts (WRCs) still present the highest activity in homogeneous photocatalytic hydrogen production The search for earth-abundant alternatives is usually limited by the time required to screen new catalyst combinations; however, here, we utilize newly designed and developed high-throughput photoreactors for the parallel synthesis of novel WRCs and colorimetric screening of hydrogen evolution. This unique approach allowed rapid optimization of photocatalytic water reduction using the organic photosensitizer Eosin Y and the archetypal cobaloxime WRC [Co(GL1)2pyCl], where GL1 is dimethylglyoxime and py is pyridine. Subsequent combinatorial synthesis generated 646 unique cobalt complexes of the type [Co(LL)2pyCl], where LL is a bidentate ligand, that identified promising new WRC candidates for hydrogen production D. functional theory (DFT) calculations performed on such cobaloxime derivative complexes demonstrated that reactivity depends on hydride affinity. Alkyl-substituted glyoximes were necessary for hydrogen production and showed increased activity when paired with ligands containing strong hydrogen-bond donors. Using a newly developed method of H2 detection using colorimetric tape, we screened a massive parallel library of cobaloxime water reduction catalysts. This noble-metal-free system of photocatalytic water reduction was optimized using Eosin Y as a photosensitizer. Screening identified a series of intriguing heteroleptic species with high activity, while DFT calculations of potential reaction intermediates correlated the activity of homoleptic cobaloximes to their hydride binding affinity.
