Synthesis Of Carbon Nanotubes Via Decomposition Of Methane Using Carbon Supported Catalysts

Carbon nanotubes (CNTs) with their special properties find applications in many areas. Owing to its global demand, its synthesis at a cheaper cost is inevitable. In this study, low-cost carbon materials like carbon molecular sieves (CMS-G, CMS-IN) and activated carbon (AC) were examined as supports for three different active metals (Ni, Co and Fe) for methane chemical vapour decomposition (m-CVD) process to produce CNTs. Blank studies and active metal impregnated (5, 10 and 15 wt% loadings) catalysts activity were studied at temperatures 650, 750 and 850 oC for maximum methane (CH4) conversion and optimum CNTs growth
