WebJul 18, 2024 · The chiral Pt NPs have an onset potential of 0.92 V at −0.1 mA⋅cm −2 (Fig. 3C), which is modestly higher (30 mV) than that found for the commercial Pt/C and significantly higher (80 mV) than the achiral Pt NPs. Moreover, chiral Pt NPs also exhibit a higher half-wave potential (0.87 V) than that of achiral NPs (0.80 V) and Pt/C (0.84 V).
