Fe2B is a potentially promising electrocatalyst for the oxygen evolution reaction (OER) due to its excellent electronic conductivity, which superior that of traditional oxide catalysts. However, activity still not satisfactory. In this study, meta-stable microstructure stacking faults (SFs) were incorporated into through one-step high-pressure and high-temperature (HPHT) method. Pressure suppressed atomic diffusion but formed SFs when grain grew. with exhibited remarkable OER activity, low overpotential values only 269 344 mV required reach current densities 10 100 mA cm−2, respectively; because presence SFs, was reduced 67.7% without at cm−2. Theoretical experimental investigations confirmed these regulate d-band center toward Fermi level, optimizing catalytic site activity. Furthermore, charge transfer between Fe atoms boron (B) atoms, increasing number free electrons in structure thereby conductivity. Finally, study suggests strategy construct microstructures crystals, providing new insights designing catalysts via engineering.

The development of highly active metal-based single-atom catalysts (SACs) is crucial for energy conversion and storage, offering optimized atom utilization high catalytic activity, with bifunctional SACs hydrogen evolution (HER) oxygen evolution/reduction (OER/ORR) reactions providing greater efficiency cost-effectiveness than monofunctional catalysts, making them scientifically economically valuable. By integrating density functional theory machine learning methods, we systematically evaluated the potential TM–N2@C15N5S3H5 monolayers as efficient HER/OER/ORR revealing that 27 TM atoms remain stable on N2@C15N5S3H5 a TM–N2 coordination environment. Rh–N2@C15N5S3H5 outperforms Pt in HER, while drives both HER OER, Ni–N2@C15N5S3H5 catalyzes OER ORR, catalysts. Comparative activity analysis reveals Ni-d orbitals interact O-p orbitals, pairing up electrons from antibonding states into downward bonding thus fitting OH* adsorption enhancing performance. We further examined pH applied effects OER/ORR performance monolayers, show enhanced acidic conditions, excelling ORR under alkaline conditions conditions. Moreover, techniques were to explore correlation between range structural atomic properties.

Electrocatalytic water splitting is a critical approach for achieving carbon neutrality, playing an essential role in clean energy conversion. However, the slow kinetics of oxygen evolution reaction (OER) remains major bottleneck hindering conversion efficiency. Although noble metal catalysts (e.g., IrO2 and RuO2) show excellent catalytic activity, their high cost scarcity limit applicability large-scale industrial processes. In this study, we introduce novel electrocatalyst based on selenized NiFe-layered double hydroxides (NiFe-LDHs), synthesized via simple hydrothermal method. Its key innovation lies selenization process, during which Ni atoms lose electrons to form selenides, while selenium (Se) gains electrons. This leads significant increase concentration high-valent ions, enhances electronic mobility, improves structural stability catalyst through formation Ni-Se bonds. Experimental results that NiFe-LDHs exhibit electrocatalytic performance 1 M KOH alkaline solution. (OER), achieved ultra-low overpotential 286 mV at current density 10 mA cm⁻2, with Tafel slope 63.6 dec⁻1. After 60 h continuous testing, showed almost no degradation, far outperforming conventional catalysts. These highlight potential NiFe-LDH@selenized electrolysis applications, providing effective solution efficient sustainable production.
