摘要

绿色合成金属纳米粒子被认为是一种成本效益高、环境友好的方法。本研究通过马铃薯淀粉稳定不同铜盐的化学还原，成功合成了铜纳米颗粒。采用x射线衍射(XRD)、傅里叶变换红外(FTIR)、扫描电子显微镜(SEM)和透射电子显微镜(TEM)对制备的铜纳米颗粒进行了表征，研究了稳定剂的颗粒大小、形状和官能团。结果表明，铜纳米颗粒的粒径在5 ~ 40 nm之间，具有FCC结构。利用紫外可见吸收光谱法测定了铜纳米粒子在554 nm左右的吸光度，研究了铜纳米粒子的形成速度。表面增强拉曼光谱(SERS)结果显示铜纳米颗粒的形成。

Characterization of green synthesized copper nanoparticles: A novel approach

Green synthesis of metal nanoparticles is considered to be a cost effective and eco-friendly approach. In the present study copper nanoparticles were synthesized successfully through chemical reduction of different copper salts stabilized by potato starch. The resulting copper nanoparticles were characterized by X-Ray Diffraction (XRD) spectrum, Fourier Transform Infrared (FTIR) Spectroscopy, Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) to study the size and shape of the particles and functional group of the stabilizing agent. The particle sizes are found to be in the range of 5 to 40 nm with FCC structure of copper nanoparticles. The rate of formation of copper nanoparticles was studied by using UV Visible Absorption Spectroscopy by measuring the absorbance at around 554 nm. The Surface Enhanced Raman Spectroscopy (SERS) results showed the formation of copper nanoparticles.
