Electrochemical water splitting is a promising technology for the sustainable production of green hydrogen. Large-scale hydrogen demands efficient electrocatalysts to continuously operate at large current densities. Catalyst deterioration and its peel-off are major concerns densities, resulting in subpar performance. Herein, we utilized acoustic cavitation-assisted electrodeposition synthesize highly robust NiFe NiMn oxyhydroxide catalysts oxygen evolution reaction (OER) (HER), respectively. The cavitation process led development uniform nanoscale structure, partial amorphization, formation vacancies, likely as result high-strain deformation. synthesized demonstrated excellent performance, with very low overpotentials 285 189 mV 1000 mA/cm2, OER HER cell configuration required 1.76 V only achieving 1 A/cm2 negligible after 24 h continuous operation. commercial viability developed was obtained by testing 2.5 × cm2 anion-exchange membrane (AEM) stack up 1.2 density. potentials reach industry-relevant high densities 500 mA/cm2 were 2.1 2.6 V, electrode stability electrolyzer scale investigated running from 100 total h, wherein durability robustness.

Abstract Synergistically optimizing electronic structure and exposing abundant active sites to significantly improve performance of transition metal‐based electrocatalysts is an urgent necessity remains a significant challenge. Herein, hybrid nanotubes array rich P‐vacancy V‐CoP@Cu 3 P in situ grown on copper foam (V ‐V‐CoP@Cu HNTAs/CF) fabricated for overall water splitting. The combined experimental theoretical calculations reveal that V doping‐induced vacancies lead the formation local electric field within V‐CoP heterojunction‐induced built‐in field, which can jointly accelerate electron transfer charge separation, thereby enhancing reaction kinetics. Moreover, nanotube not only increase electrochemical surface area offer superior mass transfer, but also possess superhydrophilic nature utilization efficiency electrode surfaces. Due these advantages, HNTAs/CF provide distinguished HER OER activity, by employing as bifunctional electrocatalysts, splitting device delivered current density 10 mA cm −2 at low voltage 1.46 maintained its activity without decay 200 h 1 m KOH electrolyte.
