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

Figure 6

Crystal properties: (a) X-ray diffraction pattern of CC (line a), electro-etched CC (line b), and NiCo₂O₄/CC (line c), and the onset shows the unit cell of NiCo₂O₄. XPS spectra for NiCo₂O₄ deposited onto CC: (b) Co (2p), (c) Ni (2p), and (d) O (1s), C(1s) in the support.
