Abstract

Abstract: The photocatalytic activity of green synthesized nickel oxide nanoparticles derived using Sterculia foetida leaf extract was examined by introducing into graphene oxide (GO). Graphene oxide has porous nature which might enlarge the photocatalytic execution of NiO nanoparticles. NiO nanoparticles (NiO NPs) were prepared by solution combustion method and introduced into graphene oxide (GO) synthesized by Hummers method to form NiO@GO nanocomposite. Various techniques were used for the material characterization of the above synthesized compounds such as UV, FTIR, Powder X-ray diffraction (PXRD), Transmission electron microscopy (TEM). The photocatalytic execution of NiO@GO nanocomposite on deterioration of Methylene blue (MB) and Malachite Green (MG) have been examined and the results indicate that the GO plays a critical part in the improvement of photocatalytic execution. Antibacterial activity has been carried out against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) . The synthesized NiO@GO nanocomposite accomplishes a most extreme decay efficiency of 98% for Methylene blue than Malachite green under UV-light.
