Ru single atoms are distributed on nitrogen‐doped carbon (Ru SAs/N–C), synthesized for efficient electrochemical reduction of N 2 by Rui Si, Jie Zeng, and co‐workers, as described in article number 1803498 . Ru SAs/N–C exhibits a record‐high activity for N 2 electrochemical reduction. At −0.2 V vs reversible hydrogen electrode, Ru SAs/N–C achieves a Faradaic efficiency of 29.6% for NH 3 production with a yield rate of 120.9 μ gNH 3 mg cat . − 1 h − 1, which is one order of magnitude higher than the highest value previously reported.
