dc.description.abstract© 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.This work describes the synthesis, characterization, and application of nanoneedle-shaped CuONPS/Cdot(N) nanostructures obtained by direct reaction between Cu(NO3)2 and nitrogen-doped carbon quantum dots (Cdot(N)). The CDot(N) obtained from oleylamine using the electrochemical technique of chronoamperometry was used as catalysts and directing agents in synthesizing CuONPS/Cdot(N) nanostructures. The CuONPS/Cdot(N) nanostructures were characterized using transmission electron microscopy (HR-TEM), X-ray photoelectron spectroscopy (XPS), ultraviolet spectroscopy (UV–Vis), infrared spectroscopy (FTIR), and electrochemical techniques. HR-TEM and XPS analysis has shown that CuONPS/Cdot(N) nanostructures are constituted for both CuO and Cu2O nanospecies. The printed carbon electrode was modified with CuONPS/Cdot(N) nanostructures. It was used to determine the pesticide glyphosate in PBS, pH 5.5, at a potential of E = − 0.02 V, using the differential pulse voltammetry technique with a detection limit of 11.6 nMol L−1. The printed carbon electrode was modified with CuNPS/Cdot(N) nanostructures and was also used to determine pesticides in real water samples with good performance.
