The cover picture shows multiple elements doped reduced graphene oxide (rGO) as an efficient electrocatalyst for the oxygen reduction reaction (ORR). As alternatives to Pt‐based electrocatalysts, the development of nonprecious metal catalysts with high performance in the cathodic ORR is highly desirable for large‐scale commercialization of automotive fuel cells. A simple two‐step doping method for the preparation of pentabasic (Fe, B, N, S, P)‐doped rGO as an efficient ORR catalyst has been developed. Simultaneously doping appropriate amounts of Fe and B into the ternary doped N, S, P‐rGO composite produced a synergistic effect for enhancing ORR activity, which endowed the prepared catalyst with even higher ORR performance than that of the commercial Pt/C catalyst in alkaline electrolytes. More details are discussed by Liu et al . on page 878–886.
