Description
Summary:Graphite particle from local coconut shell charcoal has recently attract researcher nowadays due to its application as natural graphite source in synthesis graphene and graphene oxide. In this research, coconut shell charcoal were used as the material to synthesis graphite particle using ball mill method. Coconut shell charcoal were mesh for control sample and also ball milled using three different speed which are 200 rpm, 300 rpm and 400 rpm. Particle size analysis shows coconut shell charcoal powder were in micro size which at ball milled speed 200 rpm reveal the smallest size z-average of 1116nm. From Raman spectroscopy, coconut shell charcoal were proved to be source material of graphite based on the existence of D-band at 1339.65 cm-1, G-band at 1589 cm−1 and 2D-band at 2681 cm−1.Structural properties of graphite particle were analysed using x-diffraction and it was confirmed that the structure of graphite were amorphous based on the broad band occur at 2Theta 19° to 30°.
