Nickel‐Nitrogen‐Modified Graphene: An Efficient Electrocatalyst for the Reduction of Carbon Dioxide to Carbon Monoxide

Nickel-nitrogen-modified graphene (Ni-N-Gr) is fabricated and Ni-N coordination sites on Ni-N-Gr as active centers effectively reduce CO2 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.
