Electrochemical performance of HEPBA/CNT and HEPBA/CNT-T. (a) XRD patterns of HEPBA, HEPBA/CNT, HEPBA-800, and HEPBA/CNT-800. (b) OER polarization curves of HEPBA, HEPBA-800, CNT-800, HEPBA/CNT-800, and RuO2 in the O2-saturated 1 M KOH electrolyte. (c) Tafel slope from the OER LSV curves. (d) Electrochemical impedance spectra (EIS). (e) ORR polarization curves of HEPBA, HEPBA-800, CNT-800, NCNT, HEPBA/CNT-800, and Pt/C using the RDE system in O2-saturated 0.1 M KOH under 1600 rpm rotation. (f) Comparison of the bifunctional electrocatalysts based on HE-material reported in partial literatures.
