Abstract

ABSTRACT:
Carbon nanotubes were synthesized over Catalysis of the composition 40Strontium hexaferrites SHF (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 oC which give 367 yield %. The second type of experiments was done at variable decomposition temperature and constant reduction temperature at 600 oC. The highest yield % was found at reduction and decomposition temperature 600 and 700 oC respectively (436.9%). The structure and morphology of the synthesized CNTs were characterized using high resolution transmission electron microscopy (HRTEM).
