Abstract – Carbon nanotubes (CNTs) and graphene have built broad interest in most areas of science and engineering because of their extraordinary physical, mechanical, thermal and optical properties. Graphene is a two-dimensional one-atom-thick planar sheet of sp2-bonded carbon atoms while CNTs are a cylindrical nanostructure which composed entirely of sp2-bonded carbon atoms as well. This review presents and discusses the past and current advancement of synthesis and characterization of graphene and CNTs. The review also concludes with a brief summary and an outlook on the challenges and future
prospects in the growth of graphene and CNTs.

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.
