Vertically Oriented FeNiO Nanosheet Array for Urea and Water Electrolysis at Industrial-Scale Current Density

ACS Sustainable Chemistry & Engineering, Год журнала: 2024, Номер 12(22), С. 8340 - 8352

Опубликована: Май 17, 2024

In addressing the challenging quest for an efficient electrocatalyst in electrochemical water splitting, we demonstrate Fe-doped NiO nanosheet array anchored on nickel foam synthesized via a two-step process. Demonstrating exceptional performance alkaline electrolyte, FeNiO catalysts exhibit oxygen evolution reaction with low potential of 1.52 V vs RHE and urea oxidation 1.32 @ 10 mA/cm2. The bifunctional electrolyzer generates mA/cm2 current at 1.95 1.59 electrolysis ambient temperature. Promisingly, catalyst based hydrogen industrial-scale density 400 cell voltage just 1.91 concentrated electrolyte elevated temperature (80 °C) due to dimensionally stable robust behavior self-supported catalyst. activation energy is found be 52 kJ/mol. present also 300 4 M KOH 50 °C more than 20 h. synergy induced by Fe doping into activates catalytic sites, expediting charge transfer kinetics. research report highlights as practical cost-effective approach green production splitting.
