Summary: This study presents a facile method for synthesizing ultrathin CoFe-based LDHs and reveals their high performance in OER. The Co site is identified as the main active center, and the doping of Fe accelerates the charge-transfer process. Surface Co sites are found to be the active centers for OER, while excessive subsurface Fe doping weakens OH* adsorption and increases the energy barrier of the rate-determining step.

Summary: In this study, erbium-doped NiFe layered double hydroxide (Er-NiFe LDH) nanostructures were synthesized using a simple liquid-phase method. The resulting Er-NiFe LDH exhibited higher catalytic activity and stability compared to undoped NiFe LDH and commercial RuO2 powders in electrocatalytic oxygen evolution reaction (OER). Additionally, the Er-NiFe LDH@CP electrode showed improved electrochemical durability due to stronger mechanical binding between the nanostructures and the carbon paper substrate. These findings provide an effective approach for enhancing the catalytic activity and stability of polymetallic OER catalysts in the future.

Summary: We evaluated the intrinsic activity of Ni(OH)2, NiFe layered double hydroxides (LDHs), and NiFe-LDH with oxygen vacancies for oxygen evolution reaction (OER) using cavity microelectrodes (CMEs) with controllable mass loading. The number of active Ni sites (NNi-sites) was quantitatively correlated with OER current, showing that the introduction of Fe sites and vacancies increased the turnover frequency (TOF). Electrochemical surface area (ECSA) was also quantitatively correlated with NNi-sites, indicating a decrease in NNi-sites per unit ECSA (NNi-per-ECSA) due to the introduction of Fe sites and vacancies. Therefore, the difference in OER current per unit ECSA (JECSA) was reduced compared to TOF. The results demonstrate that CMEs provide a reliable platform for evaluating intrinsic activity with TOF, NNi-per-ECSA, and JECSA.

Summary: LDHs have been identified as promising electrocatalysts for OER due to their high intrinsic activity, excellent stability, and low cost. The active edge facet of LDHs plays a crucial role in improving OER activity, with higher edge facet area ratio showing superior performance. Density functional theory calculation indicates that the edge facet exhibits higher OER activity compared to the basal plane facet.

Summary: In this study, the photocatalytic oxidative coupling of methane (OCM) over transition-metal-loaded ZnO photocatalysts was systematically investigated. A 1 wt% Au/ZnO catalyst exhibited remarkable C-2-C-4 hydrocarbon production rate and selectivity under light irradiation. The selectivity towards C-C coupling products strongly depends on the metal type and its interaction with ZnO. The findings suggest that the d-sigma center can be a suitable descriptor for predicting product selectivity during OCM over metal/ZnO photocatalysts.

Summary: Transition-metal-based oxyhydroxides are efficient catalysts for biomass electrooxidation, but the identification of active sites is still challenging. In this study, cobalt oxyhydroxide (CoOOH) was used as an archetype, and the electrocatalytic glucose oxidation reaction (GOR) was used as a model reaction to track the dynamic transformation of the catalyst's electronic and atomic structure. Two types of reducible Co3+-oxo species were identified, including adsorbed hydroxyl on Co3+ ion (mu(1)-OH-Co3+) and di-Co3+-bridged lattice oxygen (mu(2)-O-Co3+). Theoretical calculations revealed that mu(1)-OH-Co3+ was responsible for oxygenation, while mu(2)-O-Co3+ mainly contributed to dehydrogenation, both playing crucial roles in the glucose-to-formate transformation. This work provides a framework for understanding the complex near-surface chemistry of metal oxyhydroxides in biomass electrorefining.

Summary: In this study, a highly stable cathode material, hierarchical carbon nanosheet-confined defective MoSx (CNS@MoSx), was developed for aqueous zinc-ion batteries (ZIBs). The CNS@MoSx cathode exhibits excellent cycling stability with a high capacity retention rate of 88.3% and close to 100% Coulombic efficiency after 400 cycles at 1.2 A.g(-1), outperforming bare MoS2. The superior electrochemical properties of CNS@MoSx are attributed to the unique porous conductive structure of CNS, which provides abundant active sites for strong chemical bonding with MoSx, ensuring its firm confinement on the substrate. Additionally, the hierarchical complex structure enables fast migration of Zn2+ within the MoSx interlayer.
