Weiyuan Ding et al.

Summary: In this study, FeCo nanoparticles, MNx (M = Fe, Co), and FePx were embedded in porous and graphitized carbon nanotubes (CNTs)/carbon nanofiber (CNF) using electrospinning and chemical vapor deposition (CVD) techniques. The prepared FeCo@CoNx@FePx/C exhibited a high half-wave potential of 0.86 V in oxygen reduction reaction (ORR) and a low oxygen evolution reaction (OER) overpotential of 368 mV at 10 mAmiddotcm(-2). The assembled Zn-air battery (ZAB) showed a high energy efficiency of 65% at 20 mAmiddotcm(-2) and remained stable for 700 charge-discharge cycles. This work has important implications for the design of bifunctional electrocatalysts.

Engineering Self-Supported Hydrophobic-Aerophilic Air Cathode with CoS/Fe3S4 Nanoparticles Embedded in S, N Co-Doped Carbon Plate Arrays for Long-Life Rechargeable Zn-Air Batteries

Lei Yan et al.

Summary: A hydrophobic-aerophilic strategy is developed to engineer the reaction kinetics at air cathodes by fabricating a self-supported air cathode based on CoS/Fe3S4 nanoparticles encapsulated in S, N co-doped carbon plate arrays (CoS/Fe3S4@SNCP).

F. F. Alharbi et al.

Summary: The slow kinetics of water-splitting reaction and the need for improved oxygen evolution reaction (OER) electrocatalysts have been identified as major barriers to hydrogen production from water. This study investigates the effectiveness of inexpensive manganese bichalcogenide heterostructures and their equivalents, manganese oxide (MnO) and manganese sulfide (MnS), as electrocatalysts for water splitting. Various techniques such as powder X-ray diffraction (PXRD), Fourier transform infrared (FTIR) spectroscopy, and scanning electron microscopy (SEM) are employed to study these electrocatalysts. The results show that the MnS/MnO electrocatalyst exhibits remarkable efficiency and stability, outperforming other rare earth metal and Mn-based electrocatalysts under identical electrochemical conditions. The stability analysis indicates that the fabricated nanohybrids remain stable for 30 hours after 1000 cycles. This innovation provides a promising non-noble metal electrocatalyst for OER.
