- Carbon microspheres (C-mS) were successfully synthesized from used lube oil as the carbon source using thermal chemical vapor deposition method. The nature present of carbon content in used lube oil promoted the growth of C-mS. The oil mixed with 5,33 wt% of ferrocene catalyst was initially heated at 450 °C in the precursor furnace and then transferred into deposition furnace at 900 °C by the flow of argon carrier gas. The collected sample was then analyzed using field emission scanning electron microscope (FESEM) and micro-Raman spectroscopy. The current-voltage (IV) profile of the C-mS was also studied using four-point probe measurement. FESEM and micro-Raman analyses showed the production of high density C-mS with diameter range of 0,57 – 3,14 mm and ID/IG ratio of 0,95. Semiconductor characteristic was observed from IV measurement indicated that the C-mS synthesized from used lube oil has potential to be applied in electronic devices. This study noted that the used lube oil can be used as an economical carbon source to replace the conventional chemical precursor to produce high quality carbon material. On the other hand, it also offered a new utilization of used lube oil which can be harmful to our environment.
