An electrochemical synthesis strategy has been approached to prepare the novel composite viz.reduced graphene oxide nanosheets/ZnO microspheres (~0.6 µm)-Au nanoparticles (~50 nm) modified glassy carbon electrode (GCE/RGO/ZnO-Au) for the trace level detection of hydrazine. The as-prepared composite is characterized by using Scanning Electron Microscopy (SEM) along with Energy Dispersive X-ray (EDX) analysis confirm the presence of Au nanoparticles along with globular ZnO microspheres embedded over the entire surface of graphene nanosheets. The electrochemical detection of hydrazine is performed by using cyclic voltammetry and chronoamperometry methods. Fascinatingly, the oxidation peak current of hydrazine at RGO/ZnO-Au modified GCE is 4.1 fold higher than that of RGO-Au modified GCE and 2.4 fold higher than ZnO/Au-modified GCE along with favorable lower overpotential at 0.1 V. The chronoamperometric hydrazine sensor shows a very lower detection limit of 18 nM with higher sensitivity of 5.54 µA µM -1 cm -2 . The excellent analytical parameters of the RGO/ZnO-Au modified electrode over the various related modified electrodes suggests that the electrode can be widely used for the trace level detection of hydrazine for several industrial applications with low cost, ease of preparation, repeatability and long-term stability.
