Electrochemical performance of Co3Ta/C electrocatalyst for hydrazine oxidation reaction. a HzOR polarization curves of Co3Ta/C intermetallic NPs at different hydrazine concentrations. b LSV curves of Co3Ta/C, the precursors, Co/C, XC-72, commercial Ir/C, and commercial Pt/C in 3 M KOH solution with 0.2 M hydrazine. c The Tafel slopes of Co3Ta/C NPs, Co/C NPs, and commercial Pt/C; Co3Ta/C NPs quickly increase the current density for the HzOR. d HzOR performance comparisons of Co3Ta/C, Co/C, commercial Pt/C, and commercial Ir/C at different potentials. e Quantitative comparison of the current densities of Co3Ta/C NPs, Co/C NPs, and commercial Pt/C before and after constant applied potential for 12,000 s; Co3Ta/C NPs are remarkably stable
