Article Preview

Carbon nanofibers (CNFs) with different compositions (MgONixCoy, x and y= 0.0 to 0.5) and morphologies were synthesized by the CVD method using H2/C2H2 gas over a bimetallic MgO supported catalyst. The techniques such as Raman spectroscopy, SEM and TEM were used to characterize the as-synthesized nanofibers. The maximum yield for the longest of CNFs having widest diameter was obtained with MgONi0.0Co0.5 catalyst at 600°C, while bi-metallic composition MgONi0.25Co0.25 produced CNFs with good crystalline features. The nanostructure of the CNFs with MgONi0.5Co0.0 generates onion/flake like structure.
