Abstract
In this study, we discussed the synthesis of Pt doped NiO decorated single wall carbon nanotubes nanocomposite (Pt-NiO/SWCNTs/NC) and investigated the effect of this nanocomposite on the reduction of charge transfer resistance (Rct) in electrochemical systems (solution of 1.0 mM [Fe(CN)6]3-/4-+0.1 M KCl). For this goal, we synthesized the NiO nanoparticle, NiO/SWCNTs nanocomposite and Pt/SWCNTs nanocomposite and then morphological of these nanocomposites were characterized by TEM method. The effect of these nano-compounds on the reduction of charge transfer resistance was compared with Pt-NiO/SWCNTs/NC. The results demonstrated that, the synthesized nanomaterials could be reduce charge transfer resistance in redox reaction. Also, the Pt-NiO/SWCNTs/NC (diameter, ~ 15-20 nm) showed best condition for reduction of charge transfer resistance compare to other nanomaterials. This point confirmed that doping of Pt into NiO nanostructure and decoration of this nano-hybrid on surface of SWCNTs created high conductivity nanomaterials that are useful for fabrication of electro-catalyst in fuel cell systems.
