Keywords:Palm oil, Carbon materials, Plasma discharge, Tocotrienols

Carbon materials was successfully synthesized from palm oil—the richest natural source of Tocotrienols—by discharging the plasma in the oil, at room temperature and atmospheric pressure. The plasma was generated by bipolar-pulsed power supply through two tungsten electrodes using different pulse widths (1 and 2 ms) and frequencies (15, 25, 40, and 50 KHz) for 20 min. We report herein the effect of the plasma discharge conditions on properties of the obtained carbon. It was observed that after plasma discharge, the palm oil was converted to carbon powder which were then separated from the liquid phase before analyzing for their properties using transmission electron microscopy (TEM), X-ray diffraction (XRD), and Raman spectroscopy. Production yield of the obtained carbon with different conditions was also investigated.
