Electrocatalytic Oxidation of Hydrazine Based on NiHCF@TiO2 Core-Shell Nanoparticles Modified GCE

A thin film of nickel hexacyanoferrate incorporated titanium oxide modified electrode has been successfully synthesized by depositing NiHCF in TiO2 nanoparticles which was synthesized by sol-gel method. The DRS-UV, FT-IR, SEM, EDAX and XRD techniques were adopted to characterize the structure and properties of the nanocomposite (NiHCF @TiO2 NP). The [email protected]2 NPs modified GCE shows an excellent electrocatalytic activity towards the oxidation of hydrazine in PBS. A calibration plot was constructed for quantitative detection of hydrazine using DPV technique with the concentration ranges from 0.2μM to 1μM. The detection limit (3σ) for hydrazine was found to be 1.1×10-7M.
