Figure 4. Polarization curves of Mn-VS2, Mn-VS2-Ox-5 and Mn-VS2-Ox-60 measured in (A) 0.5 M H2SO4, (B) 1 M PBS, (C) 1 M KOH, and (D) simulated seawater with iR compensation at 95%; (E) Overpotentials of Mn-VS2, Mn-VS2-Ox-5 and Mn-VS2-Ox-60 at current densities of -10 and -100 mA·cm-2 in different environments.
