Catalytic efficiency of GO-PANI nanocomposite in the synthesis of N-Aryl-1,4-Dihydropyridine and hydroquinoline derivatives

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: Jan. 22, 2025

Abstract In this research, graphene oxide-polyaniline (GO-PANI) nanocomposite was successfully synthesized and its catalytic performance evaluated for the synthesis of N-aryl-1,4-dihydropyridine (1,4-DHP) hydroquinoline derivatives. The GO nanosheets were prepared using Hummers’ method, in-situ polymerization aniline conducted with ammonium persulfate (APS) serving as initiator. demonstrated notable efficiency, achieving yields 80–94% 1,4-DHP derivatives 84–96% GO-PANI thoroughly characterized by various techniques, including Fourier Transforms Infrared spectroscopy (FT-IR), Field Emission Scanning Electron Microscopy (FE-SEM), X-ray Diffraction analysis (XRD), Thermogravimetric (TGA), Energy Dispersive (EDS), all which confirmed successful nanocomposite. Furthermore, after ten cycles reusability testing, retained high no significant degradation. This findings indicate that is a promising non-metal catalyst

Sensitive Electrochemical Sensor Based on Amino-Functionalized Graphene Oxide/Polypyrrole Composite for Detection of Pb2+ Ions

Chemosensors, Journal Year: 2025, Volume and Issue: 13(2), P. 34 - 34

Published: Jan. 24, 2025

In this work, an amino-functionalized graphene oxide/polypyrrole (AMGO/PPy) composite-based novel sensing platform was established to monitor lead ions (Pb2+) at high sensitivity. AMGO synthesized through a hydrothermal process and later formed composite with PPy varying concentrations. A physicochemical investigation of the materials carried out using various characterization tools, while electrochemical properties were examined by cyclic voltammetry (CV), differential pulse (DPV), impedance spectroscopy (EIS) methods. The AMGO/PPy deposited on glassy carbon electrode (GCE), which used for real-time detection Pb2+. sensor exhibited lower limits (LOD) 0.91 nM. addition, developed Pb2+ excellent reproducibility, repeatability, selectivity, sensitivity, long-term stability 25 days. emerges as ground-breaking material Pb2+, holding significant potential environmental monitoring protection human health.
