摘要：以蔗渣为原料,采用硝酸铁、二茂铁、草酸钴对蔗渣进行预处理,制备蔗渣-催化剂前体。在微波场中,700W功率下对蔗渣-催化剂前体进行裂解制备生物质基碳纳米管(CNTs),并通过X射线衍射、扫描电子显微镜、拉曼光谱等多种表征方法分析碳纳米管微观结构。结果表明,通过金属催化剂预处理后,MCN-2和MCN-3产品管壁上可以观察到完整且光滑的CNTs。拉曼光谱中I_(D)与I_(G)的比值远低于1.0,表明制备的CNTs石墨化程度较高。与生物质炭相比,CNTs的结晶度、结构有序性和热稳定性增加。
The sugarcane bagasse was pretreated with iron nitrate,ferrocene,and cobalt oxalate to prepare sugarcane bagasse catalyst precursor.Bio-based carbon nanotubes(CNTs)were prepared by pyrolysis of bagasse catalyst precursor in a microwave field at a power of 700W,and the microstructure of the CNTs was analyzed by various characterization methods such as X-ray diffractometer,scanning electron microscope,Raman spectroscopy,etc.The results showed that after pretreatment with metal catalysts,the smooth CNTs could be observed on the tube walls of MCN-2 and MCN-3 products.The ratio value of I_(D) and I_(G) in Raman spectroscopy was much lower than 1.0,indicating a high degree of graphitization of the prepared CNTs.Compared with bio-char,CNTs had increased crystallinity,structural order,and thermal stability.
