摘要: In this work, a novel nanocomposite containing silver nanoparticles (AgNPs) embedded poly(1-naphthylamine) nanospheres (Ag/PNA) was prepared by in situ chemical reduction of nitrate. The structure, composition, and morphology the Ag/PNA nanocomposites were established Fourier transform infrared spectrometry, X-ray diffraction, scanning electron microscopy, transmission microscopy. electrochemical properties PNA Ag/PNA-modified carbon paste electrodes analyzed using cyclic voltammetry (cyclic voltammogram) impedance spectroscopy. It is observed that charge transfer characteristics have significantly enhanced upon incorporation AgNPs. has shown impressive electrocatalytic sensing performance toward H2O2. Remarkably, present Ag/PNA-based enzymeless voltammetric H2O2 sensor showed wide detection range concentration 1–3000 μM with lower limit 0.972 μM. study revealed are an ideal platform for fabrication low-cost non-enzymatic high sensitivity, good reproducibility, better selectivity, stability.
