本研究采用化学气相沉积法,以氢氧化铝为载体负载铁为催化剂,通过催化裂解乙炔合成了碳微球,并详细探讨了催化剂以及碳微球的沉积区域对所合成的碳微球的直径的影响,通过场发射扫描电镜、能谱分析、高分辨投射电镜对产物形貌和超微观结构进行了表征和分析。结果显示,催化剂和沉积区域在某种程度上对碳微球的直径起到了一定的控制作用。
In this study, the chemical vapor deposition method, aluminum hydroxide supported iron as a catalyst, the catalytic cracking of acetylene synthesis of carbon microspheres, and discussed in detail the deposition of the catalyst and the microspheres on the diameter of the synthesized carbon microspheres The morphology and microstructure of the product were characterized and analyzed by field emission scanning electron microscopy, energy dispersive spectroscopy and high resolution transmission electron microscopy. The results show that the catalyst and the deposition area to some extent play a certain role in the control of the diameter of the carbon microspheres.
