Abstract

A highly efficient catalyst for Li–O₂ batteries based on Ru and MnFe phosphides nanoparticles entrapped in a MnFe Prussian blue analogue (PBA) substrate (Ru-MnFeP/PBA) was explored. Synergy between homogeneous Ru and MnFe phosphides nanoparticles improved the catalytic activity and alleviated side reactions. The Li–O₂ battery based on Ru-MnFeP/PBA exhibited excellent performance.
