In this study, NiCo nanoparticles were synthesized on functionalized multiwalled carbon nanotubes using the chemical reduction method. The electrochemical and electrocatalytic behavior of NiCo@f-MWCNT towards glucose oxidation was investigated using various techniques. The results showed that NiCo@f-MWCNT nanocomposites exhibit excellent sensitivity and stability, making them suitable for electrochemical detection of glucose.
NiCo (Nickel-cobalt) nanoparticles were obtained by the chemical reduction method on functionalized multiwalled carbon nanotubes. After this process, chronoamperometry, cyclic voltammetry, and amperometric methods were used to investigate the electrochemical and electrocatalytic behavior of NiCo@f-MWCNT against glucose oxidation. In addition, the NiCo@f-MWCNT nanocomposites were analyzed by characterization techniques such as X-Ray Diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Transmission Electron Microscopy (TEM), and Atomic Force Microscopy (AFM) in terms of the morphological and atomic structure of prepared nanomaterials. The sensitivity and limit of detection the non-enzymatic glucose sensor (NiCo@fMWCNT) were calculated as 10,015 mu A/mM-1 cm-2 0.26 mu M, respectively. As a result of these studies and experiments, the NiCo@f-MWCNT nanocomposite is a really good sensor and their stability showed that the current nanomaterials expressed to be new material for the electrochemical detection of glucose.
