dc.description.abstractThe work focused on the use of kaolin as support material for the development of Fe/Kaolin monometallic catalyst for multi-walled carbon nanotubes synthesis (MWCNTs) in catalytic vapour deposition equipment. The influence of process parameters such as drying temperature, drying time, stirring speed and mass of support on the percentage yield of monometallic Fe/Kaolin catalyst using wet impregnation method was further reported using a factorial experimental approach. The optimum yield of 79.40% was obtained at a drying temperature of 120°C, drying time of 5 hours, stirring speed of 700 rpm, and 9 g mass of support during the optimization of the process parameters. The highest yield catalyst was then characterized for surface area, morphology, functional group, and crystallinity using BET, SEM/EDX, FTIR and XRD respectively. The well characterized catalyst was further used for the synthesis of MWCNTs in a CVD reactor and the effect of acetylene flow rate on the MWCNTs yield was recorded. It was found that the flow rate of acetylene was directly proportional to the MWCNTs yield. The synthesized MWCNTs possessed excellent morphology and surface area. Hence, the applied kaolin support showed high proficiency for possible application as catalyst support for synthesis of good quality MWCNTs in a CVD reactor.
