Synthesis of Tin Doped Copper Oxide Nanocomposites for Electrochemical Sensor Application

Abstract

Poly (Tin-doped copper oxide nanocomposites modified glassy carbon electrode) (Poly (Sn-doped CuO nanocomposite)-MGCE) made sensors were confirmed by electrochemical finding of norepinephrine (NE). The Sn-doped CuO nanocomposites were made by precipitation technique. This nanocomposite was described through scanning electron microscope and X-ray diffraction methods. To find the doped properties of the Poly (Sn-doped CuO nanocomposite)-MGCE were studied by cyclic voltammetry studies. The above studies prove that the altered electrodes have wide electroactive external area, and the reduction and oxidation peak appeared at pH 7.4 supportive electrolyte concentration 0.2 M phosphate buffer solution. Poly(Sn-doped CuO nanocomposite)-MGCE as limit of detection was low value for NE was found to be 2.22 µM and the limit of quantification values for NE was appeared as 7.41 µM, wide linear range, high sensitivity (20 to 350 µM), functional to the injection mockup analysis and the attained outcomes are acceptable, excellent reproducibility displays excessive potential in practical applications.
