FACILE SYNTHESIZE OF GRAPHENE OXIDE BY MODIFIED HUMMER’S METHOD AND DEGRADATION OF METHYLENE BLUE DYE UNDER VISIBLE LIGHT IRRADIATION.

Abstract

Graphene is a very huge and ultimate material for composite with metals, semiconductors and non metals in recent years, due to its has a unique atom-thick with two-dimensional (2D) structure, excellent physical properties like high conductivity and charge mobility, huge specific surface area, excellent mechanical, thermal and electrical properties. Thus, it has been regarded as an important component for functional materials, especially for developing a variety of catalysts and it has been considered widely as a prominent precursor and a starting material for the synthesis of this processable material. This work describes the synthesis of Graphene oxide (GO) by Modified Hummer’s method and characterization of GO by Ultra violet visible spectroscopy (UV-Vis), UV-visible diffuse reflectance spectroscopy (UV-DRS), X-ray diffraction (XRD), Field emission scanning electron microscopy (FESEM) and Energy dispersive spectroscopy (EDX) analysis. The results obtained from the characterization techniques mentioned above is also explained in detailed and evaluation of catalytic application to environmental remedies, such as water purification of degradation of methylene blue under visible light irradiation.
