Figure 9. (A) LSV curve and (B) Tafel plot, (C) corresponding overpotentials at J = 10 and 50 mA·cm^-2; (D) comparison of mass activity under different overpotentials of the ECM@Ru and compared samples in 0.5 M H₂SO₄ acid electrolyte; (E) Corresponding capacitive ΔJ/2 as a function of scan rate; (F) Nyquist plots of ECM@Ru and CM@Ru.
