Synthesis, Magnetic and Surface Properties of Reduced Graphene Oxide Supported Nickel Oxide Hybrid Nanomaterials

Abstract:

This study focuses on the preparation and characterization of Nickel oxide nanoparticles (NiONPs) supported on the reduced graphene oxide (r-GO) surface by a simple ultra-sonochemical method (r-GO-NiONPs). The formation of the r-GO was confirmed by FT-IR spectroscopy. The layer content of the r-GO was characterised by Raman spectroscopy. The crystalline nature and average particle size of the NiONPs were inferred by Powder-XRD spectroscopy. The surface morphology of the prepared nanoparticle was studied by the Scanning Electron Microscopy (SEM). The total surface area of the r-GO-NiONPs was ascertained by Nitrogen gas BET adsorption isotherm. Surface area of r-GO-NiONPs is 282 m²g^-1 which is little over twice of Graphene Oxide (GO) 132 m²g^-1. The magnetic properties of the prepared r-GO-NiONPs was studied using Vibrating Sample Magnetometer (VSM). Field dependent magnetization studies of r-GO-NiONPs delivers a very promising result.
