Carbon nanotubes (CNTs) have received a considerable attention due to their unique chemical and physical properties, as well as their technological applications. Recently, there have been great interest in metal oxides decorated CNTs for applications in heterogeneous catalysts, fuel cells and biosensors. The most appealing metal oxide is a titanium dioxide (TiO2) because of great surface area, outstanding catalytic activity, powerful oxidation strength, chemical stability, good heat resistance and non-toxicity. In this study, we synthesized titanium oxide (TiO2) decorated on thiolated CNTs. The morphology and structure are also examined by transmission electron microscopy (TEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). Cyclic voltametry (CV) and amperometry were used to investigate electrochemical properties. |
