Electrochemical impedance stectroscopy: Bode plots for HySB at stationary potential (OCP) and optimum potential; Bode phase angle plot (dot lines) and Bide magnitude plot (straight line). The figure presents the Bode diagram (log|Z| vs. log f—straight lines and Phase angle vs. log f—doted lines) for the HySB sample at open circuit potential (blue lines) and optimum potential (red lines).
