The study focuses on the modulation of synthetic parameters in order to influence the size, structure, composition and arrangement of nanoparticles of cobalt. Cobalt nanoparticles were synthesized by ethanolic solution of benzildiethylenetriamine in cobalt nitrate solution at 60 °C with stirring and refluxing leads to nanoparticles of cobalt. The morphology and structure of the synthesized nanoparticles of cobalt were characterized by Transmission Electron Microscopy (TEM), Powder X-ray Diffraction (XRD), Thermal Gravimetric Analysis (TGA), QELS Data and Infrared Spectroscopy (IR). Crystalline size was 20 nm determined from the sharp peak at 2θ=25 °C from the powder XRD. TEM images of cobalt nanoparticles without reducing agent having the diameter 20 nm with spherical shape and black color.
该研究侧重于调节合成参数，以影响钴纳米粒子的尺寸、结构、组成和排列。钴纳米粒子通过在 60°C 下用苯二亚乙基三胺的乙醇溶液在硝酸钴溶液中搅拌和回流合成。通过透射电子显微镜 (TEM)、粉末 X 射线衍射 (XRD)、热重分析 (TGA)、QELS 数据和红外光谱 (IR) 对合成的钴纳米粒子的形态和结构进行了表征。从粉末 XRD 在 2θ=25°C 处的尖锐峰确定了结晶度为 20nm。没有还原剂的钴纳米粒子的 TEM 图像具有 20nm 的直径、球形和黑色。
