Designed Tri-Metallic (MnFeCo) Immobilized on the Graphene Oxide as High-Performance Electro-Catalyst for Overall Oxygen Evolution Reaction

Developing a procedure for the synthesis of metal electrocatalyst with high performance andstability are considerable important to attain overall water splitting. In this work, tri-metallic containing Co, Mnand Fe arrays grown on the surface of graphene oxide prepared using a facile method and applied as catalystfor oxygen evolution reaction (OER). This material exhibited excellent activities for OER with overpotential of۲۵۰ mV at the current density of ۱۰ mA cm-۲.
