Figure 7. (A-C) Structure schematic of Cu-N/C (A), Zn-N/C (B), and CuZn-N/C (C). (D-F) Models of EP molecule adsorbed onto Cu-N/C (D), Zn-N/C (E), and CuZn-N/C (F). (G-I) the highest occupied molecular orbitals of (G) CuN4, (H) ZnN4, and (I) CuZn-N/C with the adsorption of EP molecule. (J-L) pDOS of CuN4 (J), ZnN4 (K), and CuZn-N/C (L) with the adsorption of EP molecule. Reproduced with permission from Ref.[48] Copyright 2023, American Chemical Society.
