Abstract The metal-air battery is a form of renewable energy generation technology that produces electrochemically and can address concerns in the near future. However, state-of-the-art Pt electrocatalysts often suffer from agglomeration or detachment carbon supports under prolonged operation, eventually limiting long-term utilization batteries. In this work, nanoparticles were deposited on sulfur-doped nanocarbon to increase its stability. We first synthesized (S-doped) pristine as support...
