Abstract

This study introduces a highly efficient and straightforward method for synthesizing gold nanoparticles (AuNPs) within a glucosamine/alginate (GluN/Alg) nanocomposite via an ionotropic gelation mechanism in aqueous environment. The resulting nanocomposite, AuNPs@GluN/Alg, underwent thorough characterization using UV-vis, EDX, FTIR, SEM, TEM, SAED, and XRD analyses. The spherical AuNPs exhibited uniform size with an average diameter of 10.0 nm. The nanocomposites facilitated the recyclable reduction of organic dyes, including 2-nitrophenol, 4-nitrophenol, and methyl orange, employing NaBH₄ as the reducing agent. Kinetic studies further underscored the potential of this nanocomposite as a versatile catalyst with promising applications across various industrial sectors.

通过嵌入氨基葡萄糖/精氨酸纳米复合材料的原位合成金纳米粒子增强催化还原。

本研究介绍了一种在水环境中通过离子凝胶化机制在葡糖胺/精氨酸（GluN/Alg）纳米复合材料中合成金纳米粒子（AuNPs）的高效而简单的方法。利用 UV-vis、EDX、FTIR、SEM、TEM、SAED 和 XRD 分析对所得到的纳米复合材料 AuNPs@GluN/Alg 进行了全面的表征。球形 AuNPs 大小均匀，平均直径为 10.0 nm。纳米复合材料以 NaBH4 为还原剂，促进了有机染料（包括 2-硝基苯酚、4-硝基苯酚和甲基橙）的可循环还原。动力学研究进一步凸显了这种纳米复合材料作为多功能催化剂的潜力，在各个工业领域都有广阔的应用前景。
