- 摘要：Design and fabrication of multifunctional efficient and durable single-atom electrocatalyst is highly desirable and challenging for overall water splitting and zinc-air battery. Herein, a novel and efficient ruthenium coordinated with Cl and N single atom catalyst (Ru-Cl-N SAC) is synthesized. Electrochemical measurements disclose that the Ru-Cl-N SAC exhibits superior electrocatalytic activities toward hydrogen evolution reaction (HER), oxygen evolution reaction (OER) and oxygen reduction reaction (ORR) with long-term durability in alkaline medium. Furthermore, the overall water splitting cell requiring only 1.49 V to achieve a current density of 10 mA cm(-2) and a rechargeable zinc-air battery with a specific capacity of 804.26 mAh g(-1) and long-term durability for 360 h are fabricated based on the Ru-Cl-N SAC. The present work will pave the way for design and fabrication of novel and efficient multifunctional electrocatalysts in the realm of energy conversion and storage.
