Summary: In this study, nickel sulfide@cobalt iron-molybdenum oxide (NiS@CoFeMoO4) nanosheet heterostructures supported on nickel foam were fabricated. The as-built NiS@CoFeMoO4/NF with a sheet-on-sheet morphology delivered a current density of 10 mA cm-2 with a low overpotential of 72 and 200 mV for the hydrogen evolution and oxygen evolution reactions, respectively. The formation of a synergistic heterostructure between NiS and CoFeMoO4/NF via interfacial engineering facilitated the generation of a micro-mesoporous surface and modulation of the charge density at interfaces. Consequently, this configuration outperformed many non-precious-metal-based catalysts as an electrocatalyst for water oxidation.

Summary: Studying the changes in electrode activity and stability caused by increasing ion concentration in alkaline seawater electrolysis is essential for industrial-level seawater electrolysis. This study investigates the concentration of hydroxide ion (OH-), chlorine ion (Cl-), and other ions in alkaline seawater (OIAS) to understand the activity and stability of nickel foam (NF) electrodes in hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). Overall, the activity of HER electrode decreases with increasing OH- concentration, while the OER electrode is enhanced by increasing OH- and Cl- concentration. However, increasing ion concentrations (OH-, Cl-, and OIAS) decrease the stability of HER electrode, while Cl- reduces the stability and OH- and OIAS enhance the stability of OER electrode. Additionally, the chloride evolution reaction (ClER) in 6 M NaOH with seawater can be ignored despite reaching saturation of salt concentration in alkaline seawater.

Summary: The slow kinetics of the oxygen evolution reaction (OER) hinders the progress of water electrolysis technology and the long-term efficiency of hydrogen energy production. By creating a self-supported electrode with FeS film coated Fe foam as a substrate, ordering resoluble molybdate (MoO42-) anions in interlayers, and codoping as a catalytically active phase, an electrochemically self-reconstructing (ECSR) catalyst for OER is developed. The catalyst introduces new active sites through the dissolution of molybdate and sulfur ions, resulting in improved OER activity and stability.

Summary: Oxygen vacancies (Ov) engineering has been shown to greatly enhance electrocatalytic kinetics for oxygen evolution reaction (OER) by improving electronic transport. However, the mechanism behind this enhancement is not well understood. In this study, we investigate the role of superficial Ov in enhancing the catalytic potential of NiFe layered double hydroxides for OER. We find that superficial Ov engineering significantly reduces the charge transport resistances and modulates the utilization rate of active sites for OER catalysis.

Summary: In this study, a series of M-doped Co3O4 materials were grown on a Ni foam substrate, and it was found that doping with Ce significantly enhanced the water and urea oxidation performance, while doping with Ni and Fe reduced the performance. The experimental results suggest that the improved activity of the Ce-doped electrode can be attributed to faster electron transport capacity, higher exposure to active sites, and improved conductivity. This work provides a new approach to enhance the electrocatalytic activity of catalysts through doping strategy.

Summary: Atomically dispersed metal catalysts with high metal atom utilization and catalytic activity have been a challenge to design and prepare on a large scale, mainly due to high-temperature pyrolysis. This study presents a two-step solution using a porous metal-organic framework to spatially confine an iron precursor complex and immobilize it on a surface at a relatively low temperature. The resulting catalyst with atomically dispersed iron sites demonstrates tunable and extraordinary catalytic performance in oxygen evolution reactions, attributed to fully exposed iron sites on the surface. The fabrication method provides a facile approach for the rational design of high-performance, stable, and atomically dispersed metal-nitrogen-carbon electrocatalysts with tunable metal content.

Summary: A copper-zirconia composite with an evenly distributed lamellar structure, Cu#ZrO2, was synthesized by nanophase separation of the Cu51Zr14 alloy precursor in a mixture of carbon monoxide (CO) and oxygen (O2). High-resolution electron microscopy revealed that the material consists of alternating Cu and t-ZrO2 phases with an average thickness of 5 nm. Cu#ZrO2 displayed enhanced selectivity for the electrochemical reduction of carbon dioxide (CO2) to formic acid (HCOOH) in aqueous media, with a Faradaic efficiency of 83.5% at -0.9 V versus the reversible hydrogen electrode. In situ Raman spectroscopy showed that the interaction between Zr4+ sites and the Cu boundary led to improved reaction selectivity and a large number of catalytic sites.
