Waste cooking palm oil (WCPO) has been utilized as a green carbon source for the synthesization of graphene by double thermal chemical vapor deposition. The WCPO was placed in the first furnace (precursor furnace) whereas nickel was placed in the second furnace (deposition furnace). The deposition temperatures were varied between 850 and 1100 °C. Raman results reveal the highest 2-D peak for the sample synthesized at 1000 °C, which indicates the high-quality formation of graphene. Besides, the sample also shows good crystallinity with a sharp peak at 26.8° which represents the hexagonal graphite structure and the introduction of graphene sheet formation. On the other hand, the FESEM image displays hexagonal structures since the graphene layers were formed after the precipitation of the carbon. Meanwhile, the UV-Vis result shows the highest reflectance in the visible light region which indicates the presence of the graphene layer on Ni.

废蒸煮棕榈油作为绿色碳源用于多层石墨烯的生长

废蒸煮棕榈油(WCPO)已用作绿色碳源,用于通过双重热化学气相沉积法合成石墨烯。WCPO放置在第一炉(前驱炉)中,而镍放置在第二炉(沉积炉)中。沉积温度在850至1100℃之间变化。拉曼结果揭示了在1000°C合成的样品的最高二维峰,这表明石墨烯的高质量形成。此外,样品还显示出良好的结晶性,在26.8°具有尖锐的峰,这代表了六方石墨结构和石墨烯片形成的引入。另一方面,由于石墨烯层是在碳沉淀之后形成的,因此FESEM图像显示出六边形结构。与此同时,
