摘要

Developing highly active, stable and low-cost electrocatalysts to boost the oxygen reduction reaction (ORR) is key to the practical applications of many advanced energy technologies. In this study, a highly active, ordered mesoporous ORR catalyst was developed using cobalt coordinated 4,4′-bipyridine as a precursor. The catalyst exhibited excellent ORR performance, with a half-wave potential of 0.87 V (vs. RHE). Additionally, the catalyst also exhibited excellent methanol tolerance and stability, as well as a nearly 100% selectivity towards the four electron path during the catalytic procedures. The more mesoporous structures, higher pyridinic N contents, and high surface area, are verified and believed to be the proper origins for the catalyst's excellence performance.

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.
