Summary: Transition metal selenides have unique electronic properties and tunability, which make them attractive electrocatalysts for various applications. However, the structure evolution of cobalt selenide and its impact on catalytic activity and stability under alkaline hydrogen evolution reaction (HER) have not been fully explored. In this study, the structure evolution, catalytic activity, and stability of Co3Se4 electrodes under alkaline HER were investigated. Continuous Se leaching transforms Co3Se4 into Co(OH)2 during HER, resulting in an activation process in the early stage and a decay process later on. Addition of SeO32- ions in the electrolyte effectively inhibits Se leaching and excessive hydroxylation, enhancing stability. Mechanistic studies reveal that SeO32- added to the electrolyte can increase the concentration of SeO32- ions in the electric double layer to regulate the dynamic balance of Se leaching. This work provides insights into the structure evolution, dynamic activity regulation, and stability of electrode materials during electrochemical reduction processes.

Summary: Earth-abundant transition metal oxides, such as CoO and Co3O4, grown on carbon fiber paper (CFP) electrodes, exhibit different catalytic activities for the oxidation of glycerol, diols, and monohydric alcohols. In situ electrochemical tests show that the CoO/CFP electrode has higher catalytic activity than the Co3O4/CFP electrode, with lower interfacial impedance, higher charge transfer, and faster oxidation rate. The CoO/CFP electrode also produces value-added products with high selectivity and efficiency at low energy consumptions. Theoretical calculations highlight the importance of octahedrally coordinated Co-O sites in the adsorption, activation, and oxidation of C3-C1 alcohols. These findings provide insights for the design of highly efficient transition metal oxide catalysts for alcohol oxidation.

Summary: To address low Coulombic efficiency and premature failure in Zn metal batteries, an integrated eutectic electrolyte was used to construct a gradient organic/inorganic hybrid SEI layer on the Zn anode. This layer with a gradient structure and composition alleviates corrosion and passivation on the Zn anode, as well as inhibits dendrite growth. The results show a significantly improved Coulombic efficiency of 99.8% over 1200 cycles and a high cumulative plated capacity of 5.57 A h cm(-2) at 5 mA cm(-2).

Summary: A general electrochemical activation strategy was reported to induce phase transformation in Ni0.85Se, resulting in a core-shell structure of NiSe with low crystallinity in the core and short-range ordered Ni3Se2 on the surface. The composition and structure changes were systematically tracked, and more Se vacancies were formed, optimizing the electronic structure for efficient alkaline hydrogen evolution reaction. The phase transformation caused by electrochemical activation was found to be universal, regardless of preparation method and crystal structure, even with higher Se content.

Summary: Ni-Fe-Mo ternary alloy nanowire electrocatalysts were prepared through a magnetic field-assisted self-assembly method. These alloy electrodes exhibit spin polarization-dependent OER catalytic performance, attributed to ferromagnetic regulation. Ni0.8Fe0.15Mo0.05 shows the highest ferromagnetism and substantially improved OER activity. The favorable adsorption of oxygen-containing intermediates (OH*), composition-dependent, and enduring spin polarization contribute to the regulated OER activity. The higher magnetic properties of Ni-Fe-Mo ternary alloy nanowires contribute to in situ spin polarization at the surface.
