Optimization of CVD Synthesis conditions for Synthesis of Multiwalled Carbon Nanotubes using Response Surface Methodology

We report the successful optimization of yield of multiwall carbon nanotube synthesized by chemical vapor deposition on Fe/Mo catalyst supported on silica using Zea mays oil as the carbon source by Chemical Vapour Deposition. The response surface methodology based on Box-Behnken design was applied to investigate the effect of parameters such as reaction temperature, Catalytic ratio and Flow rate of carbon source. The significance of independent variables and their interactions were tested by means of the analysis of variance (ANOVA) with 95% confidence limits. High regression coefficient between the variables and the response showed of good evaluation of experimental data by polynomial regression model.
