| Summary: | Title screen The conversion of waste polymers into functional materials presents a promising approach for PET upcycling. In this study, we exploit PET transformed into a Laser-Induced Graphene/Al NPs/PET nanocomposite (LIMPc − Laser-Induced Metal-Polymer composite) modified with electrodeposited gold nanoparticles (AuNPs). The morphology and structure of the material were investigated by scanning electron microscopy (SEM), energy-dispersive X-ray (EDX), and X-ray photoelectron spectroscopy (XPS). The nanocomposite was employed as a flexible electrochemical sensor for the simultaneous electrochemical detection of hydroquinone (HQ) and catechol (CT). The LIMPc-plasma-NaOH-Au composite displayed well-defined oxidation peaks for HQ and CT during electrochemical analysis, with limits of detection (LOD) as low as 47 nM for CT and 56 nM for HQ, within a linear range of 0.1–300 μM for both compounds. The long-term stability of LIMPc-plasma-NaOH-Au and its performance in real sample analysis demonstrate its potential for environmental monitoring applications. Текстовый файл AM_Agreement |
