Effect of FeOx loaded on CoOx/Al2O3 catalyst for the formation of thin-walled carbon nanotubes

February 17, 2014 By Editor

Abstract – Effects of FeOx loaded on CoOx/Al2O3 catalyst on the yield and morphology of the produced carbon nanotubes were studied. The findings showed that the addition of a small amount of FeOx on the CoOx/Al2O3 catalyst provoked the formation of carbon nanotubes with a thin wall structure. The results also revealed that an increase in FeOx content decreased the yield of carbon nanotubes. An optimized weight ratio of CoOx to FeOx was found to be 8:2 (w/w) whereby the catalyst of this composition grew carbon nanotubes with a thin wall structure and not of diminutive carbon yield.

Keywords – carbon nanotubes, catalyst, electron microscopy, methane decomposition
