    Cover Picture: Synergistic Enhancement of Electrocatalytic Activity toward Oxygen Reduction Reaction in Alkaline Electrolytes with Pentabasic (Fe, B, N, S, P)-Doped Reduced Graphene Oxide (Chin. J. Chem. 9/2016) (page 849)

    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.

    Synthesis of triarylmethanes via metal-free reductive coupling of diaryl ketone, tosylhydrazide, and arylboronic acids has been developed. This methodology is realized via one-pot two-step reactions involving the preparation of N-tosylhydrazones by reacting tosylhydrazide with diaryl ketone derivatives, followed by the reductive coupling with arylboronic acid in the presence of potassium carbonate to afford various triarylmethanes analogues in moderate to good yields. Importantly, the system presented here enables the use of easily accessible starting materials and a series of substrates with diverse functional group could be tolerant in this reaction. This approach could also be particularly useful for the synthesis of triaryl-substituted carbazolyl compounds.
