Abstract

This research highlights the facile green synthesis of silver nanoparticles (AgNPs) using Phoenix dactylifera seed extracts and its photocatalytic application for the degradation of toxic dyes. The AgNPs synthesis was confirmed by the appearance of its representative absorption peak at 416 nm in UV-visible absorption spectroscopy. Moreover, the reduction of silver ions to Ag was justified through Fourier transform infrared (FTIR) spectroscopy. X-ray diffraction pattern revealed crystalline AgNPs structure with particle size ranging from 5 to 15 nm calculated using the Debye-Scherrer equation. The rectangular-like structural morphology of synthesized AgNPs was observed in scanning electron micrographs. The as-synthesized AgNPs demonstrated higher photocatalytic activity for the degradation of malachite green (MG) and congo red (CR) followed by methylene blue (MB), and crystal violet (CV) under UV irradiation. In addition, rate constant (k) and percentage degradation were also calculated. The present study presents a facile green synthesis pathway and its potentially successful manipulation in the reduction of toxic dyes under the illumination of UV-light.

利用凤凰木种子提取物降解有毒染料，实现银纳米粒子的绿色合成：表征与应用。

本研究重点介绍了利用凤凰木种子提取物轻松合成银纳米粒子（AgNPs）的绿色方法及其在降解有毒染料方面的光催化应用。在紫外可见吸收光谱中，AgNPs 在 416 纳米波长处出现了代表性吸收峰，这证实了 AgNPs 的合成。此外，傅立叶变换红外光谱（FTIR）证明了银离子还原成 Ag 的过程。X 射线衍射图显示出结晶的 AgNPs 结构，使用 Debye-Scherrer 方程计算出的粒径范围为 5 至 15 nm。在扫描电子显微镜下观察到合成的 AgNPs 呈矩形结构形态。在紫外线照射下，合成的 AgNPs 对孔雀石绿（MG）和刚果红（CR）的降解具有较高的光催化活性，其次是亚甲基蓝（MB）和结晶紫（CV）。此外，还计算了速率常数（k）和降解百分比。本研究介绍了一种简便的绿色合成途径，以及在紫外光照射下成功还原有毒染料的可能性。
