Graphical Abstract
  • explained by the aforementioned removal of carbon at the Pt-NPs surface and slower degradation of the Pt/CNW catalysts as observed in Figure 8. However, the degradation mechanisms behind the ECSA loss on both Pt/CNW and HiSPEC4000 are quite similar, as seen from the exponential decay of ECSA in Figure 8. In
