Zinc–Air Batteries: A Ternary Ni 46 Co 40 Fe 14 Nanoalloy‐Based Oxygen Electrocatalyst for Highly Efficient Rechargeable Zinc–Air Batteries (Adv. Mater. 46/2018)

Abstract

In article number 1803372, Min Gyu Kim, Sang Kyu Kwak, Jaephil Cho, and co‐workers synthesize a Ni46Co40Fe14 ternary‐nanoalloy‐based oxygen electrocatalyst for Zn–air batteries by supercritical reaction and heat treatment. Both theoretical calculation and in situ X‐ray absorption spectroscopy demonstrate that the Ni46Co40Fe14 can undergo site‐selective adsorption during oxygen reduction and evolution reactions due to the charge transfer between the transition metals, which is thought to be responsible for the high Zn–air‐battery performance.
