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.
