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.

苯甲酸、3-肼-4-甲基、乙酯修饰的金纳米颗粒在SERS传感和光催化降解染料污染物中的应用

本研究报道了具有传感和降解纺织废水中有机染料污染物双重目的的金纳米颗粒（AuNPs）的生物合成。以杨桃（Averrhoa carambola， AC）和桑葚（Morus alba， MA）果实提取物为AuNPs生物合成的还原剂和稳定剂。球形MA-AuNPs和AC-AuNPs的测量波长分别为16 nm和21 nm，表面等离子体共振峰分别为541 nm和543 nm。FTIR和拉曼光谱揭示了参与生物还原的官能团修饰。采用密度泛函理论（DFT）计算了苯甲酸-3-肼-4-甲基乙基酯（C10H14N2O2）与Au2簇之间的分子相互作用，并通过GC-MS分析证实了AC-和ma -提取物的抑制作用增强。利用工业染料（CR、MB、Rh B和CV）研究了c10h14n2o2功能化AuNPs作为表面增强拉曼散射（SERS）传感器和光催化底物的性能。

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.
