Characterization of the CP‐AFs‐Pd cathode. a) SEM images of the CP‐AFs‐Pd surface at two magnifications. b) FTIR spectra of CP, CP‐AFs, and CP‐AFs‐Pd. AFM images of c) AFs‐Pd and d) AFs on the mica surface. e) Height profiles of the red and white auxiliary lines in the AFM images of AFs‐Pd and AFs, respectively. f) Height distribution of nano‐Pd (inset showing height distribution of AFs and AFs‐Pd). g) STEM‐EDX chemical maps and h) TEM image of AFs‐Pd nanocomposites. i) HRTEM image of nano‐Pd coated on AFs, with the inset showing the SAED pattern. j) XRD patterns of CP‐AFs‐Pd, which refer to characteristic peaks of Pd (JCPDS 46‐1043) and C (JCPDS 26‐1076). k) XPS spectra of CP‐AFs‐Pd.
