Cobalt hexacyanoferrate adsorbed on TiO nanoparticles and their modified glassy carbon electrodes for electrocatalytic oxidation and amperometric determination of hydrazine.

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.
