摘　　要：目的在较为温和的条件下制备氧化铁/碳纳米复合材料。方法以纳米Fe3O4粉体为催化剂,水热催化纤维素碳化,并借助扫描电镜、透射电镜、X射线光电子能谱仪和X射线衍射仪对碳化产物进行表征分析。结果获得了粒径约为150 nm的枣核形氧化铁/碳纳米复合材料。结论通过相对温和的水热反应,纤维素被碳化形成了壳核结构的纳米产物,Fe3O4催化剂在反应过程中被氧化并成为壳核结构产物的核心。Objective To obtain Fe2 O3 / carbon nano material in a relatively mild environment. Methods Cellulose was hydro-thermally treated using nano Fe3 O4 as catalyst, the product was analyzed using scanning electron microscopy, transmission electron microscopy and X-ray diffraction. Results After 3 h of hydrothermal treatment, Fe2 O3 / carbon nano material with a size of 150 nm and a rhombic shape was obtained. Conclusion By hydrothermal treating using nano Fe3 O4 as catalyst, cellulose was carbonized and formed a core-shell nano-sized product, the Fe3 O4 catalyst was oxidized and became the core of the product.
