Abstract
Hydrogen gas generated through water electrolysis can replace fossil fuels. Thus, developing cost-effective and efficient water-splitting electrocatalysts for oxygen evolution reaction is highly important. Herein, biomass-porous-carbon-supported sulphur-doped flower-like NiFe-based alloy composites are prepared using an in situ impregnation–heat treatment technology. The spherical flower (diameter ≈ 1 μm, petal thickness ≈ 20 nm) main components are Ni0.5Fe0.5 and Fe9Ni9S16. The 800 °C heat-treated catalyst demonstrates outstanding catalytic performance in oxygen evolution reactions. At a current density of 10 mA cm−2 , it exhibits a minimal overpotential of 298.62 mV
