Summary: By controlling the volume of ionic liquid used in synthesis, the heteroatom doping and morphology of CoNi metal-organic frameworks (MOFs) are modulated to generate CoSe2-NiSe2 heterojunction structures wrapped by N, P, F tri-doped carbon (NPFC) after a selenisation process. The unique cubic porous structure of CoSe2-NiSe2/NPFC exhibits a five times higher specific surface area than the sheet-like hollow structure produced without ionic liquid. The formation of heterojunctions and doping of heteroatoms successfully lower the Delta G(H*) and Delta G(OH*) values, leading to excellent activity for HER in both acidic and alkaline solutions and outstanding performance in a flexible solid-state supercapacitor.

Summary: This study proposes a feasible ligand modulation strategy to boost the oxygen evolution reaction (OER) catalytic activity of cobalt-iron oxyhydroxide ((Fe,Co)OOH). By reducing the orbital overlap between the Fe/Co 3d and O 2p, the adsorption to oxygen-containing intermediates is weakened, which facilitates the O-2 desorption. The ligand-modulated (Fe,Co)OOH exhibits excellent OER performance with low overpotentials and high durability.

Summary: The oxygen evolution reaction plays a central role in the production of chemicals and energy carriers using electrons. Metal hydroxide-organic frameworks have been demonstrated to be a tunable catalytic platform for this reaction, with stability being dictated by π-π interactions and activity being modulated by transition metals. By combining the high tunability of enzymatic systems with known oxide-based catalysts, it is possible to achieve both high activity and stability. This study reports on the synthesis of metal hydroxide-organic frameworks that act as a tunable catalytic platform for the oxygen evolution reaction, with stability being determined by π-π interactions between adjacent stacked linkers and catalytic activity being influenced by the nature of transition metals in the hydroxides. Substituting Ni-based metal hydroxide-organic frameworks with acidic cations or electron-withdrawing linkers significantly enhances the activity of the oxygen evolution reaction, with Fe substitution achieving a mass activity of 80 A g(catalyst)(-1) at 0.3 V overpotential for 20 hours. Density functional theory calculations correlate the enhanced activity with the modulation of Ni redox and the optimized binding of oxygenated intermediates by the metal hydroxide-organic frameworks.

Summary: Two-dimensional metal-organic framework nanosheets (2D MOF NSs) have emerged as durable and efficient electrocatalysts for the hydrogen evolution reaction (HER) due to their ultrathin thickness and large surface area. However, these nanosheets are typically less conductive and tend to aggregate, which hampers their electrocatalytic efficiency. In this study, a simple and unique strategy is proposed to create electrocatalysts with multilevel nanostructures by growing carbon nanotubes (CNTs) in situ from 2D Ni-MOF NSs through calcination. The resulting catalyst exhibits enhanced HER performance, and a two-electrode system utilizing this catalyst shows good electrocatalytic activity for overall water splitting.
