Zinc–Air Batteries: A Ternary Ni46Co40Fe14 Nanoalloy‐Based Oxygen Electrocatalyst for Highly Efficient Rechargeable Zinc–Air Batteries (Adv. Mater. 46/2018)

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.
