Figure 4. The energetic pathway of (A) MOR and (B) CO poisoning on the surface of Pt₁₈Ni₂₆Fe₁₅Co₁₄Cu₂₇; The (C) bonding structure and (D) PDOS of the Pt₁₈Ni₂₆Fe₁₅Co₁₄Cu₂₇^[57]; The free-energy profiles for (E) HER and (F) HzOR on Ni₃N-Co₃N and the contrast samples^[58]. HER: Hydrogen evolution reaction; HzOR: hydrazine oxidation reaction; MOR: methanol oxidation reaction; PDOS: projected density of state.
