Iron-doped cobalt-based nanomeshes have been synthesized in a one-pot methodology. 2-Methyl imidazole (2-HMIM) acted as an etchant, while high valent iron increased the acidity of solution and helped to synthesize ultrathin (thickness 1.9–2.0 nm) two-dimensional (2D)-nanomeshes having small uniform mesopores (3.8–4.0 on basal plane with surface area pore volume. 20% iron-doped nanomesh material (Co0.8Fe0.2(OH)x) revealed best water oxidation reactivity, overpotential 314 ± 3 mV, mass activity 413 19 A/g, turnover frequency (TOF) 1.41 0.04 s–1, TOFEIS 4.15 s–1. Electrochemical results suggested that Co0.8Fe0.2(OH)x-nanomesh had double-layer capacitance 12.2 mF/cm2, corresponding roughness factor 452, i.e., ion accessibility inside nanomaterial was improved 452 times compared geometrical electrode. This remarkable reactivity due (a) active sites for at protruding edge narrow planes nanomeshes, (b) ensured vertical penetration, vacant oxidation, easy O2 release from material, (c) electrochemical impedance spectroscopy formation fast charge propagation during oxygen evolution reaction (OER) transfer electrode/electrolyte interface.

In pursuit of efficient water-splitting technologies, the development high-performing electrocatalysts is crucial, particularly for hydrogen evolution reaction (HER). addition, it paramount to adopt cost-effective approaches that leverage earth-abundant metals, together with scalable synthesis methods. this study, we introduce a approach combines facile solution corrosion technique plasma modification, thereby enhancing activity NiMo alloys. The inclusion NH3 modification plays dual role by concurrently reducing and nitriding as-synthesized hydroxide. treatment results in significant reduction HER overpotential 95 mV at 10 mA/cm2 compared its initial overpotential. This improvement attributed enhanced kinetics due substantial reductions charge transfer resistance an increased double-layer capacitance. Furthermore, catalyst demonstrates excellent stability close 120 h, highlighting potential method large-area electrocatalysts.
