摘要
In this study, the AgO/rGO nanocomposite was facile synthesized via green molecules controllable route using degrees cimum tenuiflorum leaf extract. And, we delve into the electrochemical sensing capacity of nanocomposite for the detection of both acetaminophen and 4-nitrophenols. XRD study revealed that the wider (002) rGO diffraction plane integrates with the Ag crystalline characteristic, with a nanocomposite crystallite size of 10.3 nm. degrees cimum tenuiflorum biomolecules effectively reduced the metal ions as well as graphene oxide to the expected elemental compound. The incorporation of various leaf biomolecules such as poly-phenolic and alkaloids was bonded with rGO sheet position in the form of C-OH, C-H, N-H, with C = C molecular presence. The efficient interfacial contact between Ag, O and C (rGO) were investigated using XPS, which claimed that the biomolecular group phenol (O-H) with metallic compound as C-O-Ag around 533.9 eV, which has a significant witness for biomolecules incorporations. An identifiable count of elongated spherical-shaped Ag nanoparticles was stacked as well as incorporated between the thin rGO layers with 31.5 nm of particle size was confirmed by HR-TEM analysis. The electrochemical sensing parameters for acetaminophen the proposed sensor exhibits the lowest limit of detection of 0.25 mM for the linear range of concentrations 0.005 to 0.3 mM and 4-aminophenol exhibits the lowest limit of detection of 0.012 mM for the linear range of concentrations 0.001 to 0.3 mM. Overall, this research underscores the potential of AgO/rGO as a robust and efficient platform for achieving enhanced sensitivity in electrochemical sensing applications.
