                         grown by Chemical Vapor Deposition (CVD) method. Elucidating the 
                         key characteristics of catalyst sources that affect carbon 
                         nanotubes growth is of great importance for improving and control 
                         MWCNTs morphology and structure. In this work we present a 
                         systematically study of CVD parameters, such as catalyst source, 
                         substrate morphology and temperature and how it affects carbon 
                         nanotubes synthesis. The novelty of this work lies on the catalyst 
                         composition. Two specific catalyst sources were analyzed: (i) 
                         Fe2Co and (ii) Fe2Co with ferrocene. Cyclic Voltammetry results 
                         confirmed the presence of Fe2+ in the Fe2Co with ferrocene 
                         solution. X-Ray Diffraction analysis confirmed the presence of 
                         iron particles on the substrate surface after its submission to 
                         growth conditions. Raman results suggested an improvement in 
                         carbon nanotubes crystalline quality catalyzed by Fe2Co with 
                         ferrocene. For tridimensional substrates such as fibers, the Fe2Co 
                         with ferrocene provided aligned CNTs with lower defects density 
                         noticed in Raman spectra and SEM micrographs. Finally, we 
                         corroborated the Fe2+ encapsulation relation with the growth 
                         mechanism and MWCNTs formation.",
