 This study has developed a new type of porous nitrogen-dope cobalt pyrite yokeshell nanosphere, N-COS-2-YSS, which is able to perform both oxygen evolution and oxygen reduction reactions with excellent performance. The N-COS-2-YSS exhibits enhanced activity in long-term stability in zinc-air batteries, making it a promising candidate for future applications.
