The development of high-activity electrocatalysts for water splitting that comprise only inexpensive, earth-abundant elements is critical but remains a daunting challenge. In this work, yolk-shell Ni3Fe/Ni3FeN was prepared by a spray-pyrolysis technique, which could be scaleable. The yolk-shell Ni3Fe/Ni3FeN presents excellent catalytic activity for the oxygen evolution reaction (OER) and the hydrogen evolution reaction (HER) with overpotentials of 268 and 166mV at 10mAcm(-2), respectively, and bears a prominent electrochemical durability. Overall water splitting with an electrolyzer containing the yolk-shell Ni3Fe/Ni3FeN as the cathode and anode only requires a cell voltage of 1.62V to reach a current density of 10mAcm(-2). The present research not only introduces a new route for the synthesis of advanced functional electrocatalysts for overall water splitting but also sheds light on their potential commercial applications.
