Synthesis of MnO2/Graphene Nanocomposites using Plasma Electrolysis Method for Photocatalytic Degradation of Methyl Orange Dye in Water
Main Article Content
Abstract
This report presented an effective way to synthesize MnO2/graphene nanocomposites using the plasma electrolysis method for photocatalytic degradation of methyl orange dye in water. The morphology, structure, and chemical composition of MnO2/graphene nanocomposites materials were investigated through scanning electron microscopy (SEM), Raman spectra, and Fourier-transform infrared (FTIR) spectroscopy, respectively. SEM results showed that MnO2 nanoparticles with particle sizes of 30-50 nm were attached uniformly on the surface of graphene nanosheets. The photodegradation activity was performed under UV-visible irradiation to evaluate the potential application of MnO2/graphene nanocomposites.
Keywords:
