Synthesis of nanostructured Nickel compounds on conductive metallicsubstrates
Nickel hydroxide, oxide, and sulfide films were synthesized on conductive Ni metallic substrates by solidvapor reactions, calcination and hydrothermal methods. The synthesized films were characterized by XRD, XPS, FE-SEM, UV–Vis Spectroscopy and Cyclic Voltammetry (CV). The morphological analyses o...

| Summary: | Nickel hydroxide, oxide, and sulfide films were synthesized on conductive Ni metallic substrates by solidvapor reactions, calcination and hydrothermal methods. The synthesized films were characterized by
XRD, XPS, FE-SEM, UV–Vis Spectroscopy and Cyclic Voltammetry (CV). The morphological analyses of
Ni(OH)2 and NiO films showed flower-like nanostructures with thicknesses from 20 to 40 nm; meanwhile
the NiS films exhibits nano-granular morphology. All films showed high optical reflectance in the visible
region and a sharp absorption edge below 400 nm. The specific capacitance of the Nickel compound
ranges from 134 to 311 mF cm 2 (at 20 mV s 1) suggesting potential as conductive electrodes for energy
storage and electrochemical conversion cells. |
