Summary: In this study, manganese mono-boride nanoflakes were synthesized using a simple one-pot chemical reduction method at room temperature. The influence of specific surface area and boron content on the magnetic and electrocatalytic properties of the synthesized nanoflakes was investigated. The sample with the highest specific surface area and boron content showed the best magnetic and electrocatalytic properties in the HER, while the sample with the lowest specific surface area and boron content exhibited the best electric conductivity and electrocatalytic properties in the OER.

Summary: In this work, amorphous Co-P modified NiCo2S4 nanorods were used as a bifunctional catalyst for electrocatalytic water splitting in alkaline solution. The amorphous Co-P nanosheets on the surface of NiCo2S4 decreased the energy barrier of hydrogen adsorption-desorption and H2O adsorption, leading to enhanced catalytic performance and reaction kinetics for HER and OER in alkaline media. Consequently, the amorphous/crystalline Co-P/NiCo2S4 nanoarrays exhibited superior performance for full-water-splitting compared to pure NiCo2S4, reducing the cell voltage at 40 mA cm-2 from 1.709 V to 1.665 V.

Summary: A hierarchical Co3S4/CeO2 nanorod array on cobalt foam (Co3S4/CeO2-CF) was successfully fabricated via a one-step hydrothermal method. The CeO2 nanorod was fully covered by Co3S4 nanosheets, creating a hierarchical core-shell nanostructure. The Co3S4/CeO2 nanostructure, formed through doping of CeO2 and Co3S4 during the hydrothermal process, exhibits reduced free energy barrier in OER process. The Co3S4/CeO2-CF catalyst shows excellent catalytic activity for overall water splitting and remarkable stability, promising potential for bifunctional electrocatalysis.

Summary: Research has found that cathodes in lithium-ion batteries with anionic redox experience issues such as oxygen release, voltage hysteresis, and sluggish kinetics. By adjusting the lithium/oxygen ratio, the electrochemical properties of these cathodes can be improved. Additionally, anionic redox processes exhibit slow kinetics and large hysteresis in comparison to fast cationic redox processes.

Summary: Constructing stable electrode/electrolyte interphase with fast interfacial kinetics is crucial for fast-charging batteries. A higher anion/solvent ratio in the electrolyte solvation structure leads to an unfavorable interphase, while a lower anion/solvent ratio improves interfacial kinetics and cycle ability. The performance of a failed cathode can be restored by triggering the decomposition of specific species.
