C
hemical Vapor Deposition (CVD) synthesis of Carbon Nanotubes (CNTs) was carried out in a self-assembled apparatus
consisting of a hot tube furnace. Magnesium oxide supported iron catalyst samples, containing varied proportions of iron
loadings were prepared using impregnation method and spread uniformly over copper strips. Ceramic boats were placed in
the furnace so as to expose the catalyst-loaded copper strips to industrial gases such as nitrogen, methane and hydrogen. Usage
of horizontal tube furnace instead of conventional CVD reactor not only reduced the cost but also added to the simplicity
of the apparatus. Additionally, ceramic boats are at least 50% cheaper than the commonly used quartz boats. FESEM tests
on the resultant samples revealed that the CNTs ranged between 19.78 nm and 30.36 nm in diameter, which validates the
nanotube structures. We demonstrate that increasing the iron loading in the catalyst samples enhanced the probability of CNT
formation: 0% iron loading yielded no CNTs, while increasing the loading to 6.5% gave way to formation of Multi-Walled
Carbon Nanotubes (MWCNTs). This study opens up an economical route for the mass production of MWCNTs.
