TiO nanoparticles (NPs) were prepared at low temperature by stepwise hydrolysis of TiF in aqueous solution at 100 °C. TiO NPs were obtained at low temperature as small size particles. Subsequently, cobalt hexacyanoferrate (CoHCF) is adsorbed on the surface of the TiO NPs through the ion exchange method. This method is simple and forms TiO/CoHCF nanocomposite. TiO interacts with KCo[Fe(CN)] which leads to the formation of TiO(OH)-Co bond; this is confirmed by a shift in the XPS analysis. The prepared TiO/CoHCF nanocomposite has been characterized by FT-IR spectrum, X-ray photoelectron spectra (XPS), scanning electron microscope (SEM), high resolution transmittance electron microscope (HRTEM) and energy dispersive X-ray pattern (EDX). The TiO/CoHCF nanocomposite is modified by the glassy carbon electrode (GCE) as an excellent electrocatalyst for the oxidation of hydrazine and is also used for the amperometric determination of hydrazine.
