Abstract

Free-standing single-crystalline NiFe-hydroxide nanoflake arrays grown in situ on nickel foam are synthesized using a simple hydrothermal method and they exhibit remarkable activity and durability for oxygen evolution in 1.0 M KOH, achieving a decreased overpotential of 235 mV to produce 10 mA cm−2 current density after long-term operation up to 100 h.
