Abstract:
Nanocomposites have been attaining the interest of the scientific community due to their versatile applications. In this research work nanocomposites with different weight percentages of copper oxide and graphene oxide were prepared using a chemical solution method for investigating their structural, morphological and optical properties. Copper oxide nanoparticles were produced using an aqueous precipitation process. After that CuO-GO nanocomposites were synthesized by taking different weight percentages of CuO and GO. All the samples, except one, were annealed at 500 oC. For characterization, techniques like X-ray diffraction, Scanning electron microscopy, UV-vis spectroscopy and FTIR spectroscopy were employed for examining the structural, morphological and optical behaviour of the synthesized nanocomposites. XRD results showed that nanocomposites can be indexed to the monoclinic crystal system (JCPDS 48-1548). There is an increase in the crystalline size of nanocomposite as the weight percentage of copper oxide is increased. SEM results showed homogenous incorporation of CuO into GO nanoparticles. UV-vis spectroscopy results verified the increase in band gap as the weight percentage of copper oxide increased. This leads to an incline towards the high energy side in the absorption edge which is also referred to as the quantum size effect. FTIR spectroscopy results revealed that the peaks corresponding to C-O, O-H, C-H, C-C, and C=C are the prominent peaks associated with CuOGO nanocomposites.
