Rationally Designed RGO@CuO@Mn2O3; As an Excellent Electrocatalyst for the Rapid and Real-time Detection of 2-Nitrophenol
The Rationally designed and functional electronic-structures of TMOs (precisely: Copper and Manganese) beside purposeful morphologies were prepared over modest a facile synthetic method. The physical, chemical, and crystalline characters of TMOs were scrutinized over FE-SEM, HRTEM, XRD, and Raman spectroscopic analysis; conclusively. The prepared microstructures of TMOs@RGO such as RGO@CuO@Mn2O3, CuO nanoparticles (NPs), and Mn2O3 ¬nanosheet (NSs), and rGO were examined for the quantification of 2-nitrophenol (2-NP), to evaluate the electrocatalytic ability of TMOs@RGO towards electrochemical biosensing. Beneath the satisfactory optimization, the fine reduction peak was obtained at RGO@CuO@Mn2O3/GCE stating the sensing of 2-NP, by holding the linear range of 0.5 - 126 µM, and the LOD of 0.021 µM. The applicability of the established sensor was tested on the river water and lake water, whereas the significant spike recoveries were gotten similarly.
