Abstract
1,4,7,10-Tetraazacyclododecane (L) reacts with CoCl2 to provide a mononuclear cobalt complex, [Co(L)(Cl)2]Cl 1, which has been determined by X-ray crystallography. Complex 1 can serve as a new molecular catalyst for the oxygen reduction reaction (ORR). Under −0.4 V, the H2O2 yield is almost 100% with 0.20 M KOH. Investigations show that the formation of a cobalt(III)-peroxo species, [L-Co-OO]+ in solution is responsible for O2 reduction. In particular, this cobalt(III)-peroxo species has been isolated from the electrocatalytic system as a binuclear cobalt complex, [Co(L)(μ-OH) (μ-OO)Co(L)](ClO4)42 in the solid state. We hope that these findings can provide a new ideal for the development of electrocatalysts for the ORR.

NJC (New Journal of Chemistry) is a broad-based primary journal encompassing all branches of chemistry and its sub-disciplines. It contains full research articles, communications, perspectives and focus articles. This well-established journal, owned by the Centre National de la Recherche Scientifique (CNRS) of France, has been co-published with the Royal Society of Chemistry since January 1998. NJC is the forum for the publication of high-quality, original and significant work that opens new directions in chemistry or other scientific disciplines. In addition to having a significant chemical component, work published in NJC must demonstrate that it will have an impact on areas of research other than that of the reported work.
