采用溶剂热法, 以无水三聚氯氰(C3N3Cl3)和金属钠的环己烷溶液为原料, 以氯化镍为催化前驱物, 在温度为 230℃, 压力为 1.8 MPa 的条件下成功地制备了碳氮纳米管. 通过 X 射线衍射(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)、电子衍射(ED)、电子能量损失谱(EELS)和拉曼光谱(Raman)对碳氮纳米管进行了表征. SEM 和 TEM 结果表明, 碳氮纳米管成束状的定向排列, 长度约 20~30 μm, 纳米管外径比较均匀, 约为 50~60 nm, 内径约为 30~40 nm, EELS 分析表明, 氮碳元素的原子比约为 1.00, ED 和 XRD 分析表明, 纳米管可能具有一种新的 CN 晶体结构. 同时对碳氮纳米管的形成机理进行了较为详细的探讨.
Using solvothermal method, anhydrous cyanuric chloride (C3N3Cl3) and sodium metal cyclohexane solution as raw materials, nickel chloride as a catalyst precursor at a temperature of 230 ℃, the pressure of 1.8 MPa successfully Carbon nanotubes were prepared and characterized by XRD, SEM, TEM, ED, EELS and Raman. Carbon nanotubes were characterized by SEM and TEM.The results show that the carbon nanotubes are arranged in a bundle with a length of about 20-30 μm and a relatively uniform outer diameter of about 50-60 nm with an inner diameter of about 30 ~ 40 nm, EELS analysis showed that the atomic ratio of nitrogen and carbon is about 1.00, ED and XRD analysis shows that the nanotubes may have a new CN crystal structure. At the same time, the formation mechanism of carbonitride nanotubes is more detailed Discussion.
