Abstract

In this study, Hummer's method was modified to synthesize graphene oxide (GO). GO-based nanocomposites GO/ZnO, GO/MoO₃, and GO/ZnO/MoO₃ were synthesized using co-precipitation and solid-state reaction methods. The prepared GO and nanocomposites were characterized using UV-Visible spectroscopy, scanning electron microscopy (SEM), Raman spectroscopy, and X-ray diffraction (XRD). SEM images showed distinct morphological differences among GO, GO/ZnO, and GO/MoO₃, while UV-Visible and Raman spectroscopy demonstrated the influence of ZnO and MoO₃ on the optical properties and interactions of GO. Using visible light irradiation, photocatalytic degradation studies showed improved results for the GO/MoO₃ nanocomposites. The 93% degradation of methylene blue (MB) achieved by GO/MoO₃ after 280 minutes was greater than that of GO/ZnO/MoO₃ (92% degradation at 360 minutes) and GO/ZnO (93% degradation at 340 minutes) within the same period. High efficiency photodegradation of methylene blue (MB) under visible light irradiation of GO/MoO₃ nanocomposites were shown by these findings, demonstrating their strong potential for environmental remediation applications.

期刊介绍： Journal of Fluorescence is an international forum for the publication of peer-reviewed original articles that advance the practice of this established spectroscopic technique. Topics covered include advances in theory/and or data analysis, studies of the photophysics of aromatic molecules, solvent, and environmental effects, development of stationary or time-resolved measurements, advances in fluorescence microscopy, imaging, photobleaching/recovery measurements, and/or phosphorescence for studies of cell biology, chemical biology and the advanced uses of fluorescence in flow cytometry/analysis, immunology, high throughput screening/drug discovery, DNA sequencing/arrays, genomics and proteomics. Typical applications might include studies of macromolecular dynamics and conformation, intracellular chemistry, and gene expression. The journal also publishes papers that describe the synthesis and characterization of new fluorophores, particularly those displaying unique sensitivities and/or optical properties. In addition to original articles, the Journal also publishes reviews, rapid communications, short communications, letters to the editor, topical news articles, and technical and design notes.
