“…CV of Cu 2 1 in DMF showed two reductive features, assigned as sequential Cu 2+ /Cu + and Cu + /Cu 0 metal-based reductions. 337 Adding AcOH triggers catalysis at potentials slightly positive of the proposed Cu + /Cu 0 couple. In aqueous phosphate solution (pH 6.0) an E onset of ∼−1.25 V vs Ag/AgCl was observed, and H 2 was identified after CPE in the same media with a GC WE at E appl = −1.47 V vs Ag/AgCl.…”

The synthesis of renewable fuels from abundant water or the greenhouse gas CO 2 is a major step toward creating sustainable and scalable energy storage technologies. In the last few decades, much attention has focused on the development of nonprecious metal-based catalysts and, in more recent years, their integration in solid-state support materials and devices that operate in water. This review surveys the literature on 3d metal-based molecular catalysts and focuses on their immobilization on heterogeneous solid-state supports for electro-, photo-, and photoelectrocatalytic synthesis of fuels in aqueous media. The first sections highlight benchmark homogeneous systems using proton and CO 2 reducing 3d transition metal catalysts as well as commonly employed methods for catalyst immobilization, including a discussion of supporting materials and anchoring groups. The subsequent sections elaborate on productive associations between molecular catalysts and a wide range of substrates based on carbon, quantum dots, metal oxide surfaces, and semiconductors. The molecule–material hybrid systems are organized as “dark” cathodes, colloidal photocatalysts, and photocathodes, and their figures of merit are discussed alongside system stability and catalyst integrity. The final section extends the scope of this review to prospects and challenges in targeting catalysis beyond “classical” H 2 evolution and CO 2 reduction to C 1 products, by summarizing cases for higher-value products from N 2 reduction, C x >1 products from CO 2 utilization, and other reductive organic transformations.

“…In order to increase the turnover frequency for hydrogen generation, it is necessary to use an efficient hydrogen evolution reaction (HER) catalyst. So far, several complexes that contain cobalt [5][6][7][8][9][10], iron [11][12][13], nickel [14,15], copper [16][17][18][19] and molybdenum [20][21][22] have been developed as electrocatalysts for H2 generation via the reduction of water. Compared to the studies on the electrocatalytic systems, the development of photocatalytic system intended to drive hydrogen evolution from water using visible light still remains a challenging subject [23,24].…”

The reaction of 2-ethyl-2-(2-hydroxybenzylideneamino)propane-1,3-diol (H3L) with Co(NO3)2⋅6H2O affords a dinuclear cobalt complex, [Co2(HL)2(H2O)2](NO3) 1, an efficient catalyst for both electrocatalytic and photocatalytic hydrogen evolution from aqueous buffer. 1 is a water-soluble molecular species, that is among the most rapid homogeneous catalysts for water reduction and can electrocatalyze hydrogen evolution from a neutral buffer (pH 7.0) with a turnover frequency (TOF) of 1301 mol of hydrogen per mole of catalyst per hour at an overpotential (OP) of 638 mV. Additionally, under photoirradiation with blue light (λmax = 469 nm), 1, together with ascorbic acid and [Ru(bpy)3]Cl2 (bpy = 2,2′-bipyridine) in an aqueous buffer (pH 6.0), also affords hydrogen with a remarkable turnover number (TON) of 4314 mol of H2 per mol of catalyst.
