在本工作中，使用了两种天然来源：石榴皮提取物和胭脂虫染料来合成银纳米颗粒。石榴皮提取物中的天然银络合物通过溶液相法得到纳米结构，但这种方法对胭脂红染料-银前驱体的制备效率不高，且产物高度团聚。因此，对于天然前驱体，我们研究了另一种简便的固相方法，结果表明成功地制备了尺寸分布窄、分散性好的胭脂虫染料-银前驱体纳米粒子。用X射线衍射仪(XRD)、扫描电子显微镜(SEM)、能量色散X射线显微分析(EDX)和透射电子显微镜(TEM)对产物进行了表征。
In this work, two natural sources, including pomegranate peel extract and cochineal dye were employed for the synthesis of silver nanoparticles. The natural silver complex from pomegranate peel extract resulted in nano-sized structures through solution-phase method, but this method was not efficient for cochineal dye-silver precursor and the as-formed products were highly agglomerated. Therefore, an alternative facile solid-state approach was investigated as for both natural precursors and the results showed successful production of well-dispersed nanoparticles with narrow size distribution for cochineal dye-silver precursor. The products were characterized by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Energy dispersive X-ray microanalysis (EDX), and Transmission Electron Microscopy (TEM).
