Formation of composite nanostructures with an effective hydrazine sensor and their chemical approach

Abstract

Abstract In this paper, the composite of nickel and cobalt was synthesized via nickel nitrate and cobalt nitrate hexahydrate as nickel cobalt oxide (NiCoO) processed via chemical solution approach. The chemicals such as the nickel nitrate hexahydrate, cobalt nitrate hexahydrate and sodium hydroxide were utilized to form a solution and it refluxed at ~90 °C for 60 min for formation of nanocomposite of NiCoO. Thereafter, the obtained composite of NiCoO was well characterized with the instruments such as X-ray diffraction pattern (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), fourier transform infrared (FT IR) and X-ray photoelectron spectroscopy (XPS) also with electrochemical data. The well crystalline formed nanoparticles have been employed as an electroactive material for high sensitive hydrazine sensor detection with glassy carbon electrode (GCE). The electro chemical characterization was analyzed with cyclic voltammetry (CV) data's at very low to high concentration (2 μL–2 mL/100 mL PBS), effect of scan rate was analyzed from 10 to 100 mVs−1 with NiCoO/GCE electrode. The proposed sensor and their stability are the promising features of the sensor.
