Figure 3. (A) Chronoamperometric test of the as-prepared catalysts at 0.20 V vs. RHE in 0.5 M N2H4 + 1 M KOH solution; (B) Specific activity and mass activity at 0.20 V of the as-prepared catalysts before and after accelerated durability tests (ADT) of 5000 s at 0.20 V; (C) EIS of TPH Pt-{311} NCs, OTH Pt-{111} NCs and cubic Pt-{100} NCs at 0.20 V (inset: equivalent circuit used for data analyses, Rs and Rct are the ohmic and charge-transfer resistance, respectively); (D) HzOR activities of TPH Pt-{311} NCs compared with the reference results shown in Supplementary Table 4.
