Iron–cobalt nanoparticles dispersed in indium-based MIL-68-derived carbon nanosticks for water oxidation

Abstract

FeCo-based catalysts exhibit excellent performance for the oxygen evolution reaction (OER) in terms of high activity and robust stability. Herein, the dispersed bimetallic FeCo nanoparticles can be effectively encapsulated into isostructural In-based MIL-68-derived carbon nanosticks, denoted as MIL-68-FeCo-C. They show enhanced OER performance with a small overpotential of 298 mV at 10 mA cm⁻² and a satisfactory current retention of 95.5% after 20 hours.
