Abstract

This study reports the biosynthesis of gold nanoparticles (AuNPs) for the dual purposes of sensing and degrading organic dye pollutants in textile wastewater. Fruit extracts of Averrhoa carambola (AC) and Morus alba (MA) were used as reducing and stabilizing agents in the biosynthesis of AuNPs. Spherical MA-AuNPs and AC-AuNPs measured 16 nm and 21 nm, respectively, with characteristic surface plasmon resonance peaks at 541 nm and 543 nm. FTIR and Raman spectroscopy revealed functional group modifications involved in bioreduction. Density Functional Theory (DFT) calculations were employed to investigate the molecular interaction between benzoic acid-3-hydrazino-4-methyl-ethyl ester (C₁₀H₁₄N₂O₂) and Au₂ clusters, elucidating the enhanced inhibitory action attributed to AC- and MA-extracts, as confirmed by GC–MS analysis. The C₁₀H₁₄N₂O₂-functionalized AuNPs'performance as a Surface-Enhanced Raman Scattering (SERS) sensor and photocatalytic substrate was investigated using commercial dyes (CR, MB, Rh B, and CV) in wastewater.

期刊介绍： The Journal of Materials Science: Materials in Electronics is an established refereed companion to the Journal of Materials Science. It publishes papers on materials and their applications in modern electronics, covering the ground between fundamental science, such as semiconductor physics, and work concerned specifically with applications. It explores the growth and preparation of new materials, as well as their processing, fabrication, bonding and encapsulation, together with the reliability, failure analysis, quality assurance and characterization related to the whole range of applications in electronics. The Journal presents papers in newly developing fields such as low dimensional structures and devices, optoelectronics including III-V compounds, glasses and linear/non-linear crystal materials and lasers, high Tc superconductors, conducting polymers, thick film materials and new contact technologies, as well as the established electronics device and circuit materials.
