以向日葵油的甲基酯为碳源,二茂铁为催化剂前驱体,Ar为载气,通过喷雾热解法在硅衬底上合成定向碳纳米管阵列。结果表明,在硅衬底上原位形成Fe催化剂纳米颗粒。由拉曼光谱、透射电镜图和X-射线衍射谱图显示所制定向碳纳米管阵列具有较好的石墨化程度,其直径为1 0～3 0 nm,管壁约为1 0 nm。所制定向碳纳米管阵列中残留的催化剂含量可以忽略。 Taking methyl ester of sunflower oil as carbon source, ferrocene as catalyst precursor and Ar as carrier gas, directional carbon nanotube arrays were synthesized on silicon substrate by spray pyrolysis. The results show that Fe catalyst nanoparticles are formed in situ on a silicon substrate. The Raman spectra, transmission electron microscopy (TEM) and X-ray diffraction (XRD) patterns show that the prepared carbon nanotube arrays have a good degree of graphitization with a diameter of 10-30 nm and a wall of about 10 nm. The amount of catalyst remaining in the carbon nanotube array was negligible.
