Ru-Coated metal–organic framework-derived Co-based particles embedded in porous N-doped carbon nanocubes as a catalytic cathode for a Li–O2 battery†
Abstract
Co4N/Co-NC was synthesized through pyrolysis of ZIF-67 and modified with Ru nanoparticles to form Ru-Co4N/Co-NC. The resulting Ru-Co4N/Co-NC is used as a cathode for a Li–O2 battery, which shows good electrochemical performances.
