Figure 9. (A) Schematic diagram of the excellent activity of Ni_0.2Mo_0.8N/Ni. (B) Schematic representation of the interfacial model for Ru₃Ni. (C) Schematic representation of reaction mechanism. (D) Linear sweep voltammetry (LSV) curves of MgO, Pt/MgO, and Pt/C. (E) The corresponding Tafel plots were calculated from the LSV curves of MgO, Pt/MgO, and Pt/C.
