Abstrakt: Durable Cu/NiFe(OH) x electrocatalyst was designed for hydrogen evolution reaction in alkaline media. The in situ generated Cu nanodendrites protect the NiFe(OH) x from being hydrogenated, giving it a > 1000 h lifetime for high-performance water splitting (1.51 V, 10 mA cm -2 in 1 M KOH) when coupled with a NiFe-layered double hydroxide anode.
