Figure 2

(a) Linear sweep voltammetry for as-grown MoOx/MoS2 core-shell nanowire (black curve) and after exposure to 1% Hydrazine (red curve). (b) Tafel slopes for as-grown MoOx/MoS2 core-shell nanowires (black curve), 1% hydrazine-treated nanowires (red curve), and a platinum wire (dotted black curve). (c) Linear voltammograms and corresponding (d) Tafel slope analysis of MoS2 particles before (black curve) and following exposure to dilute hydrazine (blue curve). (e) Electrochemical impedance spectroscopy (EIS) Nyquist plots of the MoS2 particles following exposure to hydrazine, with line fits shown by dotted lines. (f) High-resolution TEM (HRTEM) of 2H-MoS2 particle. Scale bar, 5 nm. (g) HRTEM of as-grown MoOx/MoS2 core-shell nanowire. Scale bar, 10 nm.
