Abstract

In this report we aimed to examine the effect of metal / metal oxide nano / micro particles on the electrochemical responds of composite, carbon paste electrode (CPE) and solid glassy carbon electrode (GCE). Therefore, three different configurations of CPE modified with titanium (IV) oxide micro particles (TiO₂-µp) and gold nanoparticles (Au-np) and three different configurations of GCE including TiO₂-µp, Au-np and manganese (IV) oxide nanoparticles were prepared. Their electrochemical performances were examined towards ferricyanide. As a result, better electrochemical results were obtained with TiO₂-µp incorporated CPE where Au-np was attached with chitosan onto the electrode surface. Also for GCE, again TiO₂-µp -p modified GCE gave the best results.

Keywords: Metal/metal oxide nanoparticles, gold nanoparticles, manganese (IV) oxide nanoparticles, titanium (IV) oxide micro particles, carbon paste electrode, glassy carbon electrode.
