Nitrogen-doped bamboo-shaped carbon nanotubes/magnesium oxide composites were prepared using a simple impregnation method. Magnesium oxide nanoparticles with different crystal morphologies were obtained using magnesium oxide powder and stearic acid precursors. The calcination of bamboo-shaped carbon nanotubes/magnesium stearate mixture in a 1:1 ratio with different temperatures (300 and 400℃) in an inert atmosphere was carried out. The prepared composites were further analyzed by X-ray powder diffraction, energy dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, specific surface area measurement, Fourier transform infrared spectroscopy, transmission and scanning electron microscopy and thermogravimetric analysis techniques. Results revealed that the characteristic morphology and the crystal structure of the composites rely primarily on the heat treatment temperature chosen. To obtain a proper crystalline magnesium oxide, at least 400℃ is required. As-prepared bamboo-shaped carbon nanotube-based composites would be an ideal candidate as a catalyst or a membrane additive material for water purification technology.

N掺杂竹状碳纳米管/氧化镁纳米复合材料的研制
使用简单的浸渍方法制备了掺氮竹形碳纳米管/氧化镁复合材料。使用氧化镁粉末和硬脂酸前驱体获得了具有不同晶体形态的氧化镁纳米颗粒。在惰性气氛中,在不同温度(300℃和400℃)下以1:1的比例煅烧竹形碳纳米管/硬脂酸镁混合物。通过X射线粉末衍射、能量色散X射线光谱、X射线光电子能谱、比表面积测量、傅里叶变换红外光谱、透射和扫描电子显微镜以及热重分析技术对制备的复合材料进行了进一步分析。结果表明,复合材料的特征形态和晶体结构主要取决于所选的热处理温度。要获得合适的结晶氧化镁,至少需要400℃。所制备的竹形碳纳米管基复合材料将成为水净化技术的催化剂或膜添加剂材料的理想候选材料。
