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 Fe₂O₄ 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, Fe₂O₄ 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 Fe₂O₃ / carbon nano material in a relatively mild environment. Methods Cellulose was hydrothermally treated using nano Fe₂O₄ as catalyst, the product was analyzed using scanning electron microscopy, transmission electron microscopy and X-ray diffraction. Results After 3 h of hydrothermal treatment, Fe₂O₃ / carbon nano material with a size of 150 nm and a rhombic shape was obtained. Conclusion By hydrothermal treating using nano Fe₂O₄ as catalyst, cellulose was carbonized and formed a core-shell nano-sized product, the Fe₂O₄ catalyst was oxidized and became the core of the product.
