In this experiment, nano carbon material was synthesized with nebulized spray pyrolysis method using
palm oil. The catalyst used in this study was ferrocene with a concentration of 0.015 g/ml; 0,020 g/ml; and
0.025 g/ml. The catalyst was contacted with carbon precursors using floating catalyst method. The carrier
gas used in this study was nitrogen gas at a rate of 1.21 sccm. Nebulized process was conducted for 30
minutes with an operating temperature of 650°C; 700°C; 750°C; 800°C; 850°C; and 900°C. In this study,
nano carbon material was synthesized by deposition directly on the walls of the tube / stainless steel
reactor so no need a substrate as a growth medium carbon nano. The characteristics of nano carbon
material was analyzed by several methods, such as SEM, EDS and XRD. The XRD analysis of carbon
sample synthesized at 0.025 g/ml catalyst and all variations of temperature showed the presence of the C
(002) and C (100) peak indicated a graphitic structures. From SEM observation, it can be seen that the
structure of carbon nano spheres were found at temperature of 700°C and mixtures of nanotubes and
nanospheres were established at temperature above 800°C. |
