Doping duo : Mesoporous graphene doped with both N and S atoms (N‐S‐G) was prepared in one step and studied as an electrochemical catalyst for the oxygen reduction reaction (ORR). The catalyst shows excellent ORR performance comparable to that of commercial Pt/C. The outstanding activity of N‐S‐G results from both the large number and the synergistic effect of the dopant heteroatoms.
