The cover feature shows the controllable synthesis of nickel single atoms embedded in nitrogen‐doped carbon nanotubes (NiSA−N‐CNT) and graphene (NiSA−N‐G). Addition of citric acid introduces amorphous carbon on the layered g‐C3N4‐Ni and, after annealing under the same conditions, NiSA−N‐G was obtained instead of NiSA−N‐CNT. NiSA−N‐G with Ni atomic loading of ∼6 wt% catalysts shows better activity and stability for the CO2 reduction reaction than NiSA−N‐CNT with Ni loading of ∼15 wt% due to the more open and exposed active sites in NiSA−N‐G. The exposed active sites are most important for the electrocatalytic activity of single atom catalysts.
