Anion exchange membrane (AEM)-based electrolysis of alkaline water using a transition metal electrocatalyst is supposed to be the effective route for next-generation pure green hydrogen production, but development suitable challenging. Herein, we report simple and scalable protocol grow highly aligned ultrathin iron(III) oxyhydroxide (lepidocrocite, γ-FeOOH) nanosheet on nickel foam (γ-FeOOH-NS-NF) at room temperature (RT) through controlled simultaneous oxidation hydrolysis in presence hydrazine. During synthesis, hydrazine plays crucial multiple roles, one which generation enormous Fe vacancies (VFe). The synthesized γ-FeOOH-NS-NF showed superior bifunctional splitting activity because its thin sheet microstructure cationic defect. Particularly high current density, it an exceptionally low overpotential 320 η1000 Tafel slope 29 OER, 309 mV 65 dec–1 HER aqueous 1 M KOH solution. For overall splitting, 10 mA cm–2 density was observed potential 1.6 V. It 98% Faradaic efficiency excellent stability continuous operation over 100 h 500 density. More importantly, electrode assembly (MEA) having both anode cathode prototype anion (AEM) electrolyzer (4 cm2) outstanding performance stability. experimental results evidenced that grown NF generated VFe are primarily responsible efficient splitting. Thus, robust synthetic technique, direct usability AEM electrolyzer, correspondingly make as industrial-scale production.

Electrocatalytic water splitting to an anodic oxygen evolution reaction (OER) and a cathodic hydrogen (HER) is believed be the most important application for sustainable generation. Being four-electron, four-proton transfer process, OER plays main obstacle same. Therefore, designing effective electrocatalyst minimize activation energy barrier research topic of prime importance. The metal–organic framework (MOF) with highly porous network considered appropriate candidate in alkaline conditions. Apart from several MOFs, bimetallic one has advantageous electrocatalytic performance due synergistic electronic interaction between two metal ions. However, MOFs have their low conductive nature, therefore, they possess charge kinetics at interface. Surface functionalization via various nanoparticles (NPs) strategy nullifying issue. In this work, we designed CoNi-based MOF that was surface-functionalized by Au NPs (Au@CoNi-Bpy-BTC) under Au@CoNi-Bpy-BTC required overpotential just 330 mV, which 56 mV lower as compared pristine MOF. Impedance analysis confirms improved conductivity interface, where possesses Rct value than CoNi-Bpy-BTC materials. Moreover, Au-decorated shows 8.5 times increase TOF noble toward surface developing electrocatalysts energy-related fields. Overall, report displays exceptional correlation decorated over surface, can regulate activity, confirmed experimental analysis.
