Morphological, Structural and Electrical Properties of Coconut Shell-based Reduced Graphene Oxide

Abstract

In this work, reduced graphene oxide (rGO) was produced by green reduction process utilizing rose water as reducing agent. Various reduction temperature were also carried out to investigate its effect to the produced rGO. Prior to the reduction process, GO was initially synthesized by Hummers’ method utilizing coconut shell (CS) as initial carbon source material. The fabricated CS-based GO and rGO were then characterized to investigate their morphological, structural and electrical properties. Based on the measurement, rGO produced by reduction process at room temperature (RT) possessed the best sample among others. rGO_RT showed the highest electrical conductivity (0,08793 ± 0,00174 mS) compared to CS-based GO or other rGO samples.
