Abstract

In this study, we introduce an synthesis technique for incorporating gold nanoparticles (AuNPs) into a magnetic nanocomposite made of glucosamine and alginate (GluN/Alg) ionotropic gelation. GluN acted as a reducing agent for gold ions, leading to the formation of AuNPs which embedded in the nanocomposite FeO@GluN/Alg. Analytical techniques confirmed the crystallite structure of the nanocomposite AuNPs/FeO@GluN/Alg, which had an average size of 30-40 nm. This nanocomposite demonstrated high catalytic efficiency in reducing 2-, 3-, and 4-nitrophenols, exhibiting rapid kinetics with pseudo-first order rate constants between 1.16 × 10 s and 2.29 × 10 s. The reduction rates and recyclability for nitrophenols followed the order: 4-nitrophenol > 2-nitrophenol ∼ 3-nitrophenol. These results indicate that the nanocomposite holds significant promise for customized applications in environment and medicine, positioning it as a highly versatile material.

摘要

在本研究中，我们介绍了一种合成技术，该技术通过离子凝胶法将金纳米颗粒（AuNPs）掺入由葡萄糖胺和藻酸盐（GluN/Alg）制成的磁性纳米复合材料中。GluN充当金离子的还原剂，导致形成嵌入纳米复合材料FeO@GluN/Alg中的AuNPs。分析技术证实了纳米复合材料AuNPs/FeO@GluN/Alg的微晶结构，其平均尺寸为30-40nm。这种纳米复合材料在还原2-、3-和4-硝基苯酚方面表现出高催化效率，呈现快速动力学，伪一级速率常数在1.16×10 s和2.29×10 s之间。硝基苯酚的还原率和可回收性顺序为：4-硝基苯酚>2-硝基苯酚∼3-硝基苯酚。这些结果表明，该纳米复合材料在环境和医学定制应用方面具有巨大潜力，使其成为一种高度通用的材料。
