(a, b) High resolution N1 XPS spectra of pristine HPCMM and HPCMM/CNT, respectively. (c) Cathodic linear sweep voltammetry scan at 5 mV s–1 in a CO2-saturated or argon-saturated aqueous 0.1 M KHCO3 solution. (d) Faradaic efficiencies for formate production vs applied potential at the HPCMM and HPCMM/CNT electrodes. Reproduced with permission from ref (43). Copyright 2017 Wiley-VCH. (e) Digital photograph of practical hydrazine fuel cell device. (f) Polarization and power density curves for direct hydrazine fuel cells using SeNCM-1000 and Pt/C as electrocalalyst at 80 °C. Test conditions: the anolyte is 6.0 M KOH + 0.5 M hydrazine hydrate with a flow rate of 1 mL min–1; the cathode is oxygen with a flow rate of 0.2 slpm. Reproduced with permission from ref (34).
