Abstract
Developing nonprecious oxygen evolution electrocatalysts that can work well at large current densities is of primary importance in a viable water‐splitting technology. Herein, a facile ultrafast (5 s) synthetic approach is reported that produces a novel, efficient, non‐noble metal oxygen‐evolution nano‐electrocatalyst that is composed of amorphous Ni–Fe bimetallic hydroxide film‐coated, nickel foam (NF)‐supported, Ni 3 S 2 nanosheet arrays. The composite nanomaterial (denoted as Ni‐Fe‐OH@Ni 3 S 2 /NF) shows highly efficient electrocatalytic activity toward oxygen evolution reaction (OER) at large current densities, even in the order of 1000 mA cm −2 . Ni‐Fe‐OH@Ni 3 S 2 /NF also gives an excellent catalytic…
