Abstract
The main functional part of the supercapacitors and nanogenerators made up of various types of nanostructured materials. The contemporary devices have been manufactured employing different kinds of nanomaterials based on nanoflake and nanowire structures. These hierarchical materials show high efficiency on engineering electrodes for supercapacitors as well as piezoelectric for nanogenerators. Here, we have successfully synthesized NiCo2O4 nanowires on ZnO nanoflakes by applying two-step hydrothermal method which is absent similar analogous to date. The microscopic analysis has shown the uniform growth of NiCo2O4 nanowires on ZnO nanoflakes. This fabricated material might be used in above mentioned purposes in the future.
