Synthesis of carbon nanotubes on zeolite and montmorillonite is presented. Prior to synthesis, minerals were enriched by particles of iron. Synthesis of carbon nanotubes was performed by hot filament chemical vapour deposition using methane as a source of carbon. A high density of carbon nanotubes was observed in the whole volume of zeolite and montmorillonite. Iron containing particles catalysing the formation and growth of carbon nanotubes were visualized at the ends of nanotubes by field-emission scanning electron microscopy in a combined mode of secondary and backscattered electrons. ⁵⁷Fe Mössbauer spectroscopy was employed to find the oxidation state of iron in Fe-montmorillonite before the synthesis of nanotubes and in the structures of nanocomposites after the synthesis. The metallic particles in the structures of nanocomposites at the ends of carbon nanotubes are characterized by Mössbauer spectroscopy mainly as ferromagnetic cementite (Fe₃C).

提出了在沸石和蒙脱石上合成碳纳米管的方法。合成之前，矿物质富含铁颗粒。碳纳米管的合成是通过使用甲烷作为碳源的热丝化学气相沉积进行的。在沸石和蒙脱石的整个体积中观察到高密度的碳纳米管。通过二次发射和反向散射电子的结合模式的场发射扫描电子显微镜在纳米管的末端观察到催化碳纳米管形成和生长的含铁颗粒。⁵⁷使用FeMössbauer光谱法在纳米管合成之前以及在合成后的纳米复合材料的结构中查找铁在蒙脱石中的铁的氧化态。碳纳米管末端的纳米复合材料结构中的金属颗粒通过Mössbauer光谱进行表征，主要表现为铁磁渗碳体（Fe ₃ C）。
