Novel Method for the Synthesis of CuO Nanoparticles: Application of Synthesized CuO Nanoparticles for Fabrication of Bisphenol an Electrochemical Sensor

In this research, the synthesis of copper oxide nanoparticles was performed using Cu(acac)2 precursor. Copper oxide nanoparticles were synthesized by combustion method. Identification of synthesized nanomaterials was performed using PXRD (powder X-ray diffraction) technique. The physical properties of synthesized materials were also evaluated using UV-Vis (ultraviolet-Visible), FT-IR analyzes. It also examined the size and morphology of the materials through the FESEM (scanning electron microscopy field) and TEM (transient electron microscopy). The energy band gap of nanomaterials was studied, with an optical band gap of about 4.58 eV. An electrochemical sensor was developed using nanoparticles that the sensor is capable of bisphenol A breaks down. The results of this sensor seem to be desirable and suggest that the oxidation peak potential of the bisphenol A at a surface of CuO nanoparticle modified carbon paste electrode (CuO/NPs/MCPE) appeared at 450 mV that was about 60 mV lower than the oxidation peak potential at the surface of the carbon paste electrode (CPE). At a best condition in voltammetric analysis, the oxidation peak current of bisphenol A showed linear dynamic range (in 0.1–400 μM) with a detection limit of 0.067 μM, using square wave voltammetry (SWV) method. The CuO/NPs/MCPE was successfully applied for the analysis of bisphenol A in food samples.
