Synthesis and Characterization of Graphene Oxide from Coconut Husk Ash

Abstract

The main aim of the present work is synthesis and characterization of graphene oxide from the agricultural raw materials of coconut husks. Graphene oxide and carbon based other nanomaterials are unique in nature and broad range of applications because of its physical, chemical and electronic properties. Graphene oxide is an important carbon based two-dimensional nanomaterial. coconut husks is considered as an agro waste and evenly burned. The coconut husk ash contains high amount of silica was removed and the remaining portion of carbonized material of graphite is highly oxidized using sulfuric acid, sodium nitrate and potassium permanganate in order to increase oxygen functional groups. The oxidized form of graphene oxide hydrophilic in nature and it can be easily dispersed in water. The synthesized graphene oxide was characterized by FT-IR, FT-RAMAN, XRD and SEM-EDAX. FT-IR and Raman spectra indicated the presence of various oxygen functional groups such as in graphene oxide.
