在甲烷催化裂解反应过程中，可以形成不同的碳纳米结构。本文介绍了在添加或不添加钴的纳米晶铁催化剂上甲烷裂解反应过程中获得的特征性纳米结构碳存款的结果。碳存款的性质通过X射线衍射、扫描电子显微镜与能量色散光谱仪设备、热重-差热分析与质谱联用、飞行时间二次离子质谱分析和表面积分析（Brunauer-Emmett-Teller等温线[BET]）来确定。结果表明，两种铁催化剂制备的炭在形貌和性质上存在显著差异，并对两种铁催化剂制备的炭纳米结构的形成机理进行了探讨。
During catalytic cracking of methane reaction, different carbon nanostructures can be formed. This paper shows the results of a characteristic nanostructured carbon deposit obtained during cracking of methane reaction over nanocrystalline iron catalysts with or without cobalt addition. The properties of the carbon deposit were determined by X-ray diffraction, scanning electron microscope with energy dispersive spectrometer equipment, thermogravimetry-differential thermal analysis coupled with mass spectrometry, time-of-flight secondary ion mass spectrometry analysis and surface area analysis (Brunauer-Emmett-Teller isotherm [BET]). Significant differences in the morphology and properties of the obtained carbon were found. The mechanism of the formation of carbon nanostructures for both iron catalysts is proposed.
