Figure 4. (A) A schematic representation of the three-electrode electrochemical testing configuration; (B) CV profile of the catalysts; (C) LSV curves of Pt NWs and Pt black; (D) Comparison of overpotentials across various materials; (E) Corresponding Tafel plots of Pt NWs and Pt black; (F) i-t curves for the electrocatalysts in HER. CV: Cyclic voltammetry; LSV: linear sweep voltammetry; NWs: nanowires; HER: hydrogen evolution reaction.
