Abstract
Abstract Graphite made from coconut shell waste has been fabricated and characterized. Coconut shell waste was obtained from two different locations, first in the lowland area with seawater environment and the second area in the highlands with the freshwater environment. The sample was then dried with two different methods by the oven and solar thermal. After the drying process, the sample was carbonized at 600 °C for 3 h using a programmable furnace. Subsequently, the sample was washed with hydrofluoric acid (HF) to reduce the impurity content of the sample. The XRD analysis shows significant differences of each sample that indicate existing of the amorphous phase, which the highest intensity of carbon graphite 2H obtained in CSBO sample (71.53%), and the least achieved in CSBM sample (55.96%). The FTIR analysis affirms the presence of various oxygen-containing functional groups such as O H, C O, C C, and C O stretching. The SEM image shows pore structure and granular particle with the different size distribution, and the EDX result confirms the percentage of carbon is 93.32%.
