Recently, graphene-based
materials decorated with metal/metal oxide nanoparticles have gained great
interest among researchers owing to their wide range of technological
applications. Herein, we have synthesised reduced graphene oxide-calcium oxide
nanocomposites (rGO-CaO) by a wet chemical route using a simple one-pot
synthesis technique. Graphene oxide was synthesised via modified Hummer’s
method and CaO nanoparticles were synthesised using a wet chemical method.
Multi-characterisation techniques like X-ray diffractometry (XRD), field
emission scanning electron microscopy (FESEM), photoluminescence (PL)
spectroscopy and UV-visible spectroscopy were employed to compare the
structural and optical properties of CaO and rGO-CaO nanocomposites.
Morphological examination revealed the growth of CaO nanoparticles onto the
surface of rGO sheets. PL emission intensity of rGO-CaO nanocomposites was
found to be greater than that of pure CaO nanoparticles. The antibacterial
activity of the prepared samples was compared using Gram-negative E. coli
bacteria.
