摘要：Al2O3担载Fe作催化剂化学气相沉积法400℃下催化裂解乙炔进行反应,反应气氛分别为氢气和氩气,产物通过60℃下36%的浓盐酸中回流进行提纯.样品通过扫描电子显微镜和高分辨透射电子显微镜进行了表征.结果表明:当反应气氛为氢气时可以一次性制备均匀性很好的薄膜,其厚度约为3～15nm,层数约8～20层,薄膜之间相互交连在一起,表面有很多褶皱,为典型的石墨烯纳米片的结构;当反应气氛为氩气时,石墨烯纳米片则变成了副产物.
The reactions were carried out at 400 ℃ using iron supported on alumina as catalyst and hydrogen and argon as carrier gas separately to prepare nano-carbon materials.The products were purified by refluxing in concentrated hydrochloric acid.The samples were examined by scanning electron microscopy and high resolution transmission electron microscopy.The results showed that graphene with thickness of 3-15 nm and 8-20 layers was obtained when using hydrogen as carrier gas.And graphene became by-products when argon was used as carrier gas.
