The rapid development of Vietnam\u2019s textile dyeing industry has fueled economic growth, yet it has brought to light the issue of organic dye contamination in wastewater, posing environmental and public health concerns. In response, our work introduces an innovative approach to address this challenge: the synthesis of Ag \u2212 Mg(OH)2<\/sub> nanocomposites using avocado peel extract (Perseaamericana) for the efficient removal of organic
dyes from wastewater. This novel method not only yields eco-friendly materials but also optimizes the use of agricultural by-products, aligning with principles of sustainability and green chemistry. By employing advanced analytical techniques, including Ultraviolet-Visible spectrophotometry (UV-Vis), X-ray diffraction (XRD), and scanning electron microscopy combined with energy-dispersive X-ray spectroscopy (SEM-EDX), the authors conducted a thorough characterization of the synthesized Ag \u2212 Mg(OH)2<\/sub> nanocomposites. The unique structural composition of the material was revealed, featuring silver nanoparticles (20 to 50 nm in diameter) evenly dispersed on Mg(OH)2<\/sub> nanorods (250 to 300 nm in length). In addition, the study explored the efficacy of these nanocomposites in the photocatalytic degradation of the cationic organic dye methylene blue (MB). A notably remarkable photodegradation efficiency was observed at 82.8% after 3 hours, with an initial aqueous MB concentration of 20 ppm and a material mass- liquid volume ratio of 8 g\/L. The findings of this research are not only scientifically relevant, but also offer tangible solutions for mitigating environmental pollution and improving the quality of life.<\/p>\n\n\n\n
