Herein, amorphous/crystalline Fe-doped CoSe was synthesized (Fe-CoSe/NF), and it exhibited high oxygen evolution reaction (OER) performance. The synergistic effect of the Fe dopant and the amorphous/crystalline structure is conducive to the formation of high valence Co 3+ and Fe 3+ active sites. Fe-CoSe/NF shows low overpotentials of 269 mV@50 mA cm -2 and 280 mV@100 mA cm -2 .
