Abstract Single‐site molecular electrocatalysts, especially those that perform catalytic conversion of N 2 to NH 3 under mild conditions, are highly desirable derive fundamental structure‐activity relations and as potential alternatives the current energy‐consuming Haber‐Bosch ammonia production process. Combining theoretical calculations with experimental evidence, it has been shown easily reducible cobalt porphyrins catalyze six‐electron, six‐proton reduction dinitrogen at neutral pH ambient conditions. Two N‐fused – CoNHF CoNHF(Br) reveal NRR activity Faradic efficiencies between 6–7.5 % yield rates 300–340 μmol g −1 h . Contrary this, much harder‐to‐reduce CoNHF(Ph) CoNHF(PE) no activity. The present study highlights significance tuning redox structural properties single‐site electrocatalysts for improved
