The green-chemical preparation of silver nanoparticles (AgNPs) offers a sustainable and environmentally friendly alternative to conventional synthesis methods, thereby representing a paradigm shift in the field of nanotechnology. The biological synthesis process, which involves the synthesis, characterization, and management of materials, as well as their further development at the nanoscale, is the most economical, environmentally friendly, and rapid synthesis process compared to physical and chemical processes. flower extract was used for the preparation of AgNPs. The synthesized AgNPs were examined by using UV-visible spectroscopy, XRD, SEM, and TEM analysis. It indicates that AgNPs were formed in good size. AgNPs were applied as a catalyst for the degradation of pollutants, such as methyl orange, Congo red, and methylene blue, which were degraded within 8-16 min. Additionally, the reduction of para-nitrophenol (PNP) to para-aminophenol (PAP) was achieved within 2 min. This work demonstrates a practical, reproducible, and efficient method for synthesizing cost-effective and stable AgNPs, which serve as active catalysts for the rapid degradation of hazardous organic dyes in an aqueous environment.
银纳米颗粒(AgNPs)的绿色化学制备为传统合成方法提供了一种可持续且环境友好的替代方案,从而代表了纳米技术领域的范式转变。生物合成过程涉及材料的合成、表征和管理,以及它们在纳米尺度上的进一步发展,与物理和化学过程相比,是最经济、环境友好且快速的合成过程。用花提取物制备AgNPs。通过紫外可见光谱、XRD、SEM和TEM分析对合成的AgNPs进行了检测。结果表明,所形成的AgNPs尺寸良好。AgNPs被用作降解污染物的催化剂,如甲基橙、刚果红和亚甲基蓝,这些污染物在8 - 16分钟内被降解。此外,在2分钟内实现了对硝基苯酚(PNP)还原为对氨基苯酚(PAP)。这项工作展示了一种实用、可重复且高效的方法来合成具有成本效益且稳定的AgNPs,其可作为活性催化剂在水环境中快速降解有害有机染料。
