摘要
摘要 利用Fe(NO3)3、Co(NO3)2和Ni(NO3)2催化剂，通过改变催化剂的种类、浓度和碳化温度，使膨胀石墨在原位形成碳纳米管。对形成的碳纳米管的微观结构、改性膨胀石墨官能团和氧化温度进行了检测和分析。本文通过 X 射线衍射（XRD）、X 射线光电子能谱仪（XPS）、拉曼光谱（Raman）、扫描电子显微镜（SEM）和热重分析-差示扫描量热仪（TG-DSC）研究和表征了催化剂浓度和类型、碳源 Carbons P 与膨胀石墨的比例以及热处理温度对膨胀石墨原位催化形成碳纳米管的影响。研究了不同实验条件对碳纳米管的形成机理和影响规律。
Study on Carbon Nanotubes of Pyrolysis Carbons P for In Situ Catalytic Formation on Expanded Graphite Surface
Fe(NO3)3, Co(NO3)2, and Ni(NO3)2 catalysts were used to form carbon nanotubes in situ from expanded graphite by changing the type, concentration and carbonization temperature of the catalysts. The microstructure, modified expanded graphite functional group and oxidation temperature of the formed carbon nanotubes were detected and analyzed. The effects of catalyst concentration and type, the ratio of carbon source Carbons P to expanded graphite and heat treatment temperature on the in-situ catalytic formation of carbon nanotubes by expanded graphite were studied and characterized by X-ray diffraction (XRD), X-ray photoelectron spectrometer (XPS), Raman spectrometer (Raman), scanning electron microscope (SEM), and thermogravimetric analysis-differential scanning calorimetry (TG-DSC) in this paper. The formation mechanism and influence rule of different experimental conditions on carbon nanotubes are studied.
