采用一种简便、快速的方法清洁、高效地合成了石墨烯纳米片（GNS）和矩形排列碳纳米管（RA-CNTs）束。这些结构形成于炉的不同热区。芝麻油是一种绿色的天然前体，首次被用作合成GNS和良好填充的RA-CNTs束的烃前体。以芝麻油为原料，二茂铁为催化剂，在800 °C的高温下，在石英管中喷雾热解合成了GNSs和RA-CNTs束。这种新的前驱体适合于合成高质量和清洁的GNS和RA-CNT束。GNS显示出包含6-8个石墨烯层的几层石墨烯的形成。FTIR光谱证实，合成的材料表面没有更多的官能团连接。这些纳米结构的生长强烈依赖于管内的温度。与G峰相比，拉曼研究显示出强烈的2D峰，表明存在GNS。研究表明，这些新的碳纳米结构合成的芝麻油是干净的碳杂质。
A facile and rapid approach was used for the clean and efficient synthesis of graphene nanosheets (GNSs) and rectangular aligned carbon nanotubes (RA-CNTs) bundles. These structures were formed at different hot zones of the furnace. The sesame oil, a green natural precursor is used first time as a hydrocarbon precursor for the synthesis of GNSs and well packed RA-CNTs bundles. GNSs and RA-CNTs bundles were synthesized by spray pyrolysis of sesame oil with ferrocene as a catalyst, inside silica tube at 800 °C. This new precursor is appropriate for the synthesis of high quality and clean GNSs and RA-CNTs bundles. GNSs show the formation of few layers graphene which contains 6–8 graphene layers. FTIR spectra confirm that there is no more functional group attached on the surface of as synthesized materials. Growth of these nanostructures strongly depends on the temperature inside the tube. Raman studies show intense 2D peak as compared to G peak, signifying presence of GNSs. The investigations reveal that these novel carbon nanostructures synthesized by sesame oil are clean from carbonaceous impurities.
