Figure 3. The cyclic voltammetry curves of (A) platinum–(nickel–cobalt layered double hydroxide) (Pt-[NiCo-LDH]-X) (X = 1, 2, 3, 4), (B) Pt-(NiCo-
LDH)-X (X = 3, 5, 6, 7), (C) Pt-(NiCo-LDH)-3, NiCo-LDH-8, Pt-Ni foam (NF)-9, and NF-10 catalysts in the mixed solution of 1 M potassium hydroxide
and 0.1 M ammonium chloride, and (D) the oxidation peak currents of all catalysts. Hg/HgO refers to mercury/mercury oxide used as the reference.
