Summary: This review summarizes prominent examples of thiomolybdate-based electro- and photocatalysis and provides a comprehensive analysis of their reactivities under homogeneous and heterogenized conditions. The study examines the active sites of thiomolybdates relevant for the hydrogen evolution reaction and discusses the shift from solution-phase to surface-supported thiomolybdates with a focus on applications in electrocatalysis and photocatalysis.

Summary: In this study, ZnO-Ti3C2 MXene nanocomposites were synthesized using a simple hydrothermal method. The nanocomposites showed excellent performance in photocatalysis and electrocatalysis applications. The synergistic effect between the 2D layered Ti3C2 and ZnO resulted in enhanced electron-hole lifetime and efficient degradation of dyes. The study also demonstrated that the nanocomposites exhibited excellent hydrogen evolution reaction (HER) performance.

Summary: The octahedrally coordinated nickel(II) complexes [Ni(L)2](ClO4)2 (1,2) with (pyridin-2-ylmethyl)amine (L1, 1) and 1-(1-methyl-1H-imidazol-2-yl)-N-(pyridin-2ylmethyl)methanamine (L2, 2) as ligands were synthesized and characterized. The electrochemical hydrogen evolution reaction (HER) in acetonitrile showed that NiI is an active redox center in strong acids like p-toluenesulfonic acid. Compared to analogous Ni complexes, these complexes demonstrated higher catalytic rates and significant TONs at relatively low overpotential, and the HER activity differences mainly arise from the pyridine and imidazole donors in 1 and 2, respectively.

Summary: A general ion exchange-induced strategy was developed to synthesize various hollow X-doped (X = Co, Mn, Cu) ZnS with tunable interior components. Abundant CoO nanoparticles integrated into doped ZnS hollow microstar as visible-light-responsive photocatalysts for efficient H-2 evolution, giving a superior H-2 evolution rate (1763.17 mu mol h(-1) g(-1)) and stable cyclability without needing any cocatalyst. The catalytic mechanism of the doped ZnS/CoO system was investigated by studying the formation of potential barriers at the p-n nanointerface and essential hydrogen evolution reaction steps.

Summary: This study presents a facile wet-chemical method for synthesizing metastable orthorhombic phase CoSe2 (o-CoSe2) and stable cubic phase CoSe2 (c-CoSe2). The phase-dependent hydrogen evolution performance of CoSe2 in photo- and electrocatalysis is demonstrated. The results show that o-CoSe2 exhibits better electrocatalytic performance while c-CoSe2 shows higher photocatalytic hydrogen evolution rate. The study provides insights into the relationship between phase structure and hydrogen evolution catalysis.

Summary: This study developed a template-assisted strategy for the synthesis of tube-like nanostructured perovskite oxides, and successfully prepared 13 catalysts with high surface areas. By systematically examining these catalysts, it was found that the OER activity in neutral solutions exhibits a volcano shape as a function of the covalency of metal-oxygen bonds. The Sm-doped LaCoO3 catalyst designed in this study showed the highest OER activity in neutral electrolytes.

Summary: The core challenge of developing cost-efficient catalysts for CO2 conversion lies in controlling its complex reaction pathways. This review gathers general principles on how natural CO2 activating enzymes utilize bimetallic strategy and how various homo- and hetero-bimetallic molecular catalysts can help understand the synergistic effect of two metal centers.

Summary: An organized strategy is revealed to control steric and electronic parameters of N-heterocyclic carbene (NHC) Ag (5-10), Au (11/12), and Ni (13/14) complexes as molecular electrocatalysts for the hydrogen evolution reaction (HER) from water. The films of complexes 10, 13, and 14 exhibited improved activity with low overpotential and high current density. The durability test showed a lower decay rate for complexes 10 and 14 after 200 cycles.

Summary: This article reports on a novel Cu2O/g-C3N4 heterostructure that exhibits both photocatalytic and electrocatalytic functions for water splitting. The heterostructure shows lower overpotential and higher photocatalytic hydrogen evolution compared to g-C3N4, thanks to increased catalytically active sites and reduced charge transfer resistance.
