以废猪油为碳源，采用电感耦合等离子体（ICP）增强化学气相沉积法（PECVD）一步合成了垂直石墨烯（VG）。废猪油分解后得到交织的少层VG片、H2等烃类气体。研究了温度、气体配比、ICP功率等工艺参数对VG纳米结构的影响，结果表明，合适的温度和H2浓度是VG片制备的必要条件。丰富的VG缺陷形成高ID/IG比（1.29），在电子显微镜观察到的致密的边缘结构一致。此外，还对PECVD法和ICP法制备的纳米碳的形貌、结晶度和润湿性进行了对比分析。本工作证明了我们的PECVD方法从丰富的天然废油中合成VG的潜力，这为将低价值的碳氢化合物升级为先进的碳材料铺平了道路。
Vertical graphene (VG) sheets were single-step synthesized via inductively coupled plasma (ICP)-enhanced chemical vapor deposition (PECVD) using waste lard oil as a sustainable and economical carbon source. Interweaved few-layer VG sheets, H2, and other hydrocarbon gases were obtained after the decomposition of waste lard oil. The influence of parameters such as temperature, gas proportion, ICP power was investigated to tune the nanostructures of obtained VG, which indicated that a proper temperature and H2 concentration was indispensable for the synthesis of VG sheets. Rich defects of VG were formed with a high ID/IG ratio (1.29), consistent with the dense edges structure observed in electron microscopy. Additionally, the morphologies, crystalline degree, and wettability of nanostructure carbon induced by PECVD and ICP separately were comparatively analyzed. The present work demonstrated the potential of our PECVD recipe to synthesize VG from abundant natural waste oil, which paved the way to upgrade the low-value hydrocarbons into advanced carbon material.
