In this research work, carbon nanofibers (CNFs) were synthesized on honeycomb monolith substrates using injection chemical vapor deposition (ICVD) technique. The effect of various wash-coated materials and catalyst promoter on the growth rate of CNFs on monolith substrates were examined. The characteristics of the synthesized CNFs-coated monolith composites were examined using Raman spectroscopy, Brunauer-Emmett-Teller (BET), thermogravimetric analysis (TGA), field emission scanning electron microscopy (FE-SEM), and Transmission electron microscopy (TEM) techniques. According to the textural characterization study, the specific surface area and pore volume of CNFs-coated monolith composites were significantly improved as compared to bare monolith which might be attributed to the growth of highly pure and aligned CNFs over monolith substrate. Besides that, the synthesized CNFs-coated monolith possessed extremely well thermal stability up to the temperature of 550 °C which was corresponded to the strong attachment of highly graphitized CNFs over monolith substrates.
在这项研究工作中，使用注射化学气相沉积（ICVD）技术在蜂窝状整体式基板上合成了碳纳米纤维（CNF）。研究了各种涂覆材料和催化剂促进剂对整体式基板上 CNF 生长速率的影响。使用拉曼光谱、BET、热重分析（TGA）、场发射扫描电子显微镜（FE-SEM）和透射电子显微镜（TEM）技术对合成的 CNF 涂覆整体式复合材料的特性进行了检查。根据结构特征研究，与裸整体式相比，CNF 涂覆整体式复合材料的比表面积和孔体积显著提高，这可能归因于高度纯净和排列整齐的 CNF 在整体式基板上的生长。此外，合成的 CNF 涂覆整体式在高达 550°C 的温度下具有极好的热稳定性，这与高度石墨化的 CNF 在整体式基板上的牢固附着相对应。
