Abstract: Carbon nanotubes were synthesised over catalysis of the composition 40SHF (SrFe₁₂O₁₉):60Al₂O₃ by the catalytic decomposition of acetylene for different reaction conditions. The kinetics of synthesis of CNTs were investigated through two types of experiments, the first was done at different temperatures. The optimum conditions for the higher yield % were found to be 600°C (367 yield %). The second type of experiments was done at variable decomposition temperature and constant reduction temperature at 600°C. The highest yield % was found at reduction and decomposition temperature 600°C and 700°C respectively (436.9%).
