Electrodeposition of Hierarchical Nanosheet of NiCo₂O₄/CC as Highly Active and Stable Electrode for Water Oxidation

Figure 5

Structural properties. TEM images and corresponding selected area electron diffraction (SAED) pattern of a NiCo₂O₄ structure peeled off from carbon cloth: (a) low-magnification of the peeled NiCo₂O₄ structure and (b) higher magnification showing that each piece of NiCo₂O₄ has semicircular particles. (c) High-resolution TEM images of the nanosheet showing the interface boundary between NiCo₂O₄ particles and (d) and (e) are the corresponding images of the SEAD pattern. (f–i) TEM elemental mapping images of the NiCo₂O₄ nanosheet showing the elemental distribution of Co, Ni, and O.
