The development of efficient electrocatalysts from Earth-abundant elements for the oxygen evolution reaction (OER) is highly desired. Here, we report the electrodeposition of a NiCo layered double hydroxide nanosheet array on graphite felt (NiCo LDHs/GF) as a 3D OER electrocatalyst. Such NiCo LDHs/GF exhibits superior electrocatalytic activity with the need for an overpotential of 249 mV to drive a current density of 20 mA cm−2 in 1.0 M KOH. It also shows strong long-term electrochemical durability with its activity being maintained for at least 24 h.
