The synthesis, characterization and application of biologically synthesized nanomaterials are an important aspect in nanotechnology.
The present study deals with the synthesis of silver nanoparticles (Ag-NPs) using the coconut water (C. nucifera) as the reducing agent. The formation of Ag-NPs was characterized by UV-Visible Spectroscopy, Scanning Electron Microscopy (SEM), EDX, X-ray Diffraction (XRD) and FTIR spectroscopy.
The synthesized Ag-NPs were predominately polydispersed. Crystalline nature of the nanoparticle in the face centered cubic (fcc) structure are confirmed by the peaks in the XRD pattern corresponding to (111), (200), (220) and (311) planes. Fourier Transform Infra-Red (FT-IR) spectroscopy analysis showed that the synthesized nanoparicles was capped with bimolecular compounds which are responsible for the reduction of silver ions.
The approach of green synthesis appears to be cost efficient, ecofriendly and easy alternative to conventional methods of silver nanoparticle synthesis.
生物合成纳米材料的合成、表征及应用是纳米技术的一个重要方面。
本研究采用椰子水(椰属)作为还原剂合成银纳米颗粒(Ag-NPs)。通过紫外可见光谱、扫描电子显微镜(SEM)、能谱分析(EDX)、X射线衍射(XRD)和傅里叶变换红外光谱(FTIR)对Ag-NPs的形成进行表征。
合成的Ag-NPs主要为多分散的。XRD图谱中对应于(111)、(200)、(220)和(311)晶面的峰证实了纳米颗粒在面心立方(fcc)结构中的晶体性质。傅里叶变换红外(FT-IR)光谱分析表明,合成的纳米颗粒被双分子化合物包覆,这些化合物负责银离子的还原。
绿色合成方法似乎是一种经济高效、环境友好且比传统银纳米颗粒合成方法更简便的替代方法。
