Pure CuO and Zn-doped CuO nanoparticles were synthesized from sol-gel process by reacting copper acetate monohydrate with a urea in distilled water at 80°C. The synthesized Samples were different concentrations but same annealing temperature at 400°C. The obtained samples were characterized by means of UV-visible spectroscopy (UV-vis), X-ray diffraction (XRD), Fourier transform-infrared spectroscopy (FT-IR), Field emission scanning electron microscopy (FE-SEM) and Energy dispersive X-ray spectroscopy (EDS). UV-visible technique used to measure the band gap of the synthesized samples. The XRD spectra of the synthesized samples confirmed the CuO nanoparticles with monoclinic structure. All the functional groups of the pure and doped synthesized samples were investigated by FT-IR analysis. The morphological and elemental estimation of the pure and Zn-doped synthesized samples were examined by FE-SEM with EDS.
通过在80°C下将一水合醋酸铜与尿素在蒸馏水中反应,采用溶胶-凝胶法合成了纯CuO和Zn掺杂的CuO纳米颗粒。合成的样品浓度不同,但退火温度均为400°C。通过紫外可见光谱(UV-vis)、X射线衍射(XRD)、傅里叶变换红外光谱(FT-IR)、场发射扫描电子显微镜(FE-SEM)和能量色散X射线光谱(EDS)对所得样品进行了表征。采用紫外可见技术测量合成样品的带隙。合成样品的XRD光谱证实了具有单斜结构的CuO纳米颗粒。通过FT-IR分析研究了纯的和掺杂的合成样品的所有官能团。通过FE-SEM和EDS对纯的和Zn掺杂的合成样品进行了形态和元素评估。
