Silver nanoparticles (AgNPs) is of great importance to scientific community due to their plethora of applications. Several plant extracts have been reported for synthesis of AgNPs. In this study, lemon grass was used as a reducing and capping agent to prepare AgNPs. The formation of AgNPs was confirmed by using UV–Vis spectra as AgNPs show a characteristic peak around 400 nm. Effect of pH, temperature and lemon grass extract to silver nitrate ratio was optimized using response surface methodology (RSM). Characterization of AgNPs was done using X-Ray Diffraction (XRD), Energy Dispersive X-Ray spectroscopy (EDX), Trasmission Electron Microscopy (TEM) and Dynamic Light Scattering (DLS). Gas Chromatography-Mass spectrometry (GC–MS), Energy Dispersive X-Ray spectroscopy and Fourier Transform-Infrared (FT-IR) spectroscopic analysis showed involvement of metabolites of lemon grass in the formation of AgNPs. Photo-catalytic activity of synthesized AgNPs was evaluated through degradation of organic pollutant methylene blue dye.

基于 GC-MS 的柠檬草代谢物分析涉及银纳米粒子的合成和亚甲基蓝光催化降解的评价

银纳米粒子 (AgNPs) 因其应用广泛而对科学界非常重要。已经报道了几种植物提取物用于合成 AgNPs。在这项研究中,柠檬草被用作还原剂和封端剂来制备 AgNPs。通过使用 UV-Vis 光谱证实了 AgNPs 的形成,因为 AgNPs 在 400 nm 附近显示出特征峰。使用响应面法 (RSM) 优化了 pH、温度和柠檬草提取物与硝酸银比例的影响。使用 X 射线衍射 (XRD)、能量色散 X 射线光谱 (EDX)、透射电子显微镜 (TEM) 和动态光散射 (DLS) 对 AgNPs 进行表征。气相色谱-质谱(GC-MS),能量色散 X 射线光谱和傅里叶变换红外 (FT-IR) 光谱分析表明,柠檬草的代谢物参与了 AgNPs 的形成。通过降解有机污染物亚甲蓝染料来评估合成的 AgNPs 的光催化活性。
