chemical growth of material takes place when ionic products exceed the solubility
products. These Cd(OH) 2 nanowires can be easily converted to CdO through heat
treatment in air. Figure 6d shows the SEM image of CdO nanowires with diameter in
the range of 40–50 nm and of ultra-high length. The synthesis procedure, structural
properties, surface adsorptivity and other properties are discussed in detail in our
earlier report (Kamble et al. 2011a, b). These smooth and ultra-long nanowires are
transferred into 1-D beaded nanowire structure on making composite with ZnO, as
shown in Fig. 6e. These wires can also act as efficient template for the synthesis of
photoactive materials. Also, we have carried out direct growth of photoactive CdSe
nanosticks by one-step electrochemical growth, as shown in Fig. 6f. CdSe is one
of the efficient visible light-absorbing photoactive material. We have successfully
synthesized high surface area nanostructures of CdSe (Kamble et al. 2017).
4 One-Dimensional Nanostructures for Energy Storage
Various materials and their different nanostructures are used in the fabrication of electrodes for energy storage devices, which has high-end properties like energy density,
power density and cycling performance. Among the various nanostructures used for
ESS electrodes, the 1-D nanostructures having shorter bi-continuous ion and electron
