The Synthesis of Graphene from Coconut Shell Charcoal

Abstract

: The hybrid coconut shell charcoal is sp 3 , after being mixed with activated carbon and heated to 600(cid:31) for 1 hour it produces sp 2 which shows the characterization of graphene. The process of making graphene in this study, namely coconut shell dried under sunlight then hydrolyzed into charcoal then mixed with activated carbon as a reducing agent at 600°C for 1 hour to produce graphene. The resulting graphene is characterized by XRD, SEM-EDX, XRF and BET. The results of the XRD analysis showed that the resulting peaks were not sharp and slightly broadened the diffraction peak at 24° and 44°. The results of SEM-EDX analysis at 4000x magnification showed smaller, thinner surface sizes and structural shapes and reduced buildup in the graphene structure. XRF analysis results show that there are still organic impurities. The results of graphene analysis with BET show the surface area of graphene 82.873 m 2 / g with a pore volume of 0.116 cc / g.
