Morphological analysis using the SEM and TEM images of Pt/CNT (a,b) and Pt/C (c,d). Electrochemical performance of the electrocatalysts: (e) cyclic voltammograms of Pt/CNT and (f) Pt/C in an acidic medium (0.5 M H₂SO₄), (g) relationship between the normalized EASA as a function of the cycle number in an acidic medium (at +0.75 V vs. reversible hydrogen electrode (RHE)), and (h) Nyquist plots of the electrocatalysts.
