Synthesis of carbon microfibers by chemical vapor deposition during the catalytic decomposition of turpentine oil

摘要: 以石墨为基体，硫酸镍为催化剂，利用化学气相沉积通过松节油的催化分解合成了微米炭纤维。利用酸处理和水洗的方法将纤维从石墨和金属杂质中分离出来。利用光学显微镜和扫描电镜发现得到的纤维直径在3μm ~5μm。同时，由于自组装的作用也生成了一些海绵状的微米纤维。

Abstract: Carbon microfibers were synthesized by chemical vapor deposition during the decomposition of turpentine oil in the presence of nickel sulfate as a catalyst precursor on a graphite host. The fibers were separated from graphite and metal impurities by acid treatment, followed by several washes with deionized water. These fibers have a diameter of approximately 3-5μm and they were studied by optical and scanning electron microscopy. A sponge-like morphology of the microfibers due to self-assembly was observed.
