Figure 1

(a) Schematic representation of exposure of MoOx/MoS2 core-shell nanowire array to dilute hydrazine under ambient conditions. (b) SEM image of as-grown MoOx/MoS2 core-shell nanowire array. Scale bar, 2 μm. (c) SEM imaging MoOx/MoS2 core-shell nanowires following dilute hydrazine treatment, showing that the overall nanowire morphology is maintained. Scale bar, 2 μm. (d) High-resolution TEM (HRTEM) of as-grown nanowire, showing thin (∼3–5 nm) MoS2 shell on a single crystal MoOx core. The MoS2 has the typical interlayer spacing of 6.2 Å, denoted in image by two parallel lines. Scale bar, 5 nm. (e) HRTEM of the MoOx/MoS2 core-shell nanowire after exposure to hydrazine. Scale bar, 5 nm.
