Figure 5. (A) Linear sweep voltammetry (LSV) curves of as-prepared catalysts BV and BVC electrodes; (B) Corresponding Tafel slopes; (C) EIS Nyquist plots 1 MHz to 10 mHz; (D and E) Cyclic voltammograms of BV and BVC; (F) Current density with respect to scan rates of BV and BVC electrodes, i.e., double layered capacitance (C_dl); (G) The actual, predicted, and forecasted chronoamperometry (CA) curve of BVC in 1.0 M KOH; (H) LSV curves for OER measured before and after CA stability at 1 mV s^-1 scan rate; (I) EIS Nyquist plots of the electrode before and after the stability test. BV: BiVO₄; BVC: bismuth vanadate/carbon; OER: oxygen evolution reaction.
