Microstructure analysis of graphene oxide synthesized from corn cobs waste

Abstract

Graphene oxide is one carbon-based material decorated by oxygen functional group that has been applied in various field. Active oxygen functional group allows graphene oxide served as precursor for many applications including DSSC, Field Effect Transistor, LED, and Transparent Conductive Film. Unfortunately, high cost of pure raw material inhibits the wide application of graphene oxide. Corn cobs is one of highly produced waste from agricultural activity that become an unsolved environmental problem. Meanwhile, high content of carbon material in corn cob allows it to be a potential carbon source for graphene oxide synthesis. In this report the synthesis of graphene oxide from corn cobs using modified hummers method is discussed. As synthesized sample was analysed using FTIR, XRD, and SEM to confirm the successful of graphene oxide form corn cobs.
