Nickel‐nitrogen‐modified graphene (Ni‐N‐Gr) is fabricated and Ni‐N coordination sites on Ni‐N‐Gr as active centers effectively reduce CO 2 to CO. The faradaic efficiency for CO formation reaches 90% at −0.7 to −0.9 V versus RHE, and the turnover frequency for CO production comes up to ≈2700 h −1 at −0.7 V versus RHE.
