Figure 8. (A) Array: schematic diagram of the array; NH3 yield of arrays formed at different oxidation times[60]; (B) Heterojunction: schematic diagram of heterojunction; NH3 yield rate of Fe SAC, Fe SAC/FeP@C, and FeSAC/FePO4[62]; (C) Schematic diagram of Ni3N/Cu; NH3 yield rate of NF/Ni3N, NF/Ni3N-Cu, NF/Ni3N-Cu NP[63]; (D) Tandem interaction of Cu(100) and Cu(111) facets[64]; the FE of NO2- to NH3 on Cu(111) at low concentration[64]. NP: Nanoparticle; FE: Faradaic efficiency.
