Title: Nitrogen and sulfur co-doped porous carbon sheets for energy storage and pH-universal oxygen reduction reaction

Abstract

Developing efficient electrocatalysts for energy storage and oxygen reduction reaction (ORR) is of great sig-nificance for the utilization of renewable energy. In particular, designing catalysts with both promising activityand long stability for ORR in pH-universal electrolytes still remain as a tremendous challenge. To tackle such aproblem, metal-free nitrogen and sulfur co-doped porous carbon sheet (NSPCS) was rationally designed in thiswork in order to integrate the two reported routes of enhancing the electrocatalytic activity of graphene. The as-prepared NSPCS has an onset potential of 0.89 V vs. RHE, and half-wave potential E1/2 ≈ 0.75 V during ORR inacidic solution, making it as the most active ORR catalyst. Moreover, the resulting NSPCS also shows a 0.03 Vpositive shift of half-wave potential than commercial Pt/C for ORR and excellent charge capacitive performancein alkaline media. Electron microscopy revealed high degree of defects on NSPCS surface. This, coupled withsynergistic doping effects of nitrogen and sulfur, optimized the active sites and charge transfer, rationalized theoutstanding performance in both oxygen reduction reactions and supercapacitors.Developing efficient electrocatalysts for energy storage and oxygen reduction reaction (ORR) is of great significance for the utilization of renewable energy.
