Single-atom catalysts (SACs) are one of the most promising candidates to catalyze various electrochemical reactions, due to the maximum atom utilizations and unique electronic structures. However, the general methods for preparing the SACs usually require complex processes, delicate regulation and special properties of the anchoring metals and supports. Herein, we for the first time develop a facile, high-efficiency and universal plasma-etching strategy to fabricate various single metal and dual metal-SACs on a variety of supports. As an example, the prepared Cu-SAC/NC exhibits superb oxygen reduction reaction (ORR) activity as well as long circulation stability. More importantly, the Cu-SAC/NC also exhibits a remarkable battery performance when implemented as the air-cathode catalysts of assembled zinc-air batteries. Furthermore, density functional theory calculations reveal that the pyrrolic-type three … |
