We introduce a simple yet effective sulfur-doped disordered carbon material that catalyzes the oxygen reduction reaction (ORR) primarily through a two-electron-transfer process. This material stands out due to its impressive performance, with all tested catalysts showing a remarkable HO2– selectivity of approximately 75%, the most positive onset potential, and the highest current density. Notably, the catalyst annealed at 1000 °C demonstrated the best electrocatalytic activity. These findings offer new insights into the ORR mechanism using sulfur-doped disordered carbon materials, highlighting their potential for efficient energy conversion processes.-Science Journal cover design by scapiens
