Oxidised charcoal: an efficient support for NiFe layered double hydroxide to improve electrochemical oxygen evolution

Abstract

We report the facile synthesis of oxidised charcoal supported NiFeLDH (NiFeLDH/OC) at room temperature. It showed unprecedented activity in the oxygen evolution reaction with an overpotential of 240 mV at 10 mA cm−2, which is ∼115 mV less than pure NiFeLDH. The electronic enrichment at the metal sites and enhanced surface area of NiFeLDH/OC are reasons for the improved activity.
