采用Polyol合成法,以三嵌段共聚物PEO-PPO-PEO为表面活性剂,以1,2-十六烷二醇为还原剂,乙酰丙酮钴(Ⅱ)、乙酰丙酮铁(Ⅱ)和醋酸金为前驱体,成功合成了CoFeAu纳米粒子.傅立叶变换红外光谱(FT-IR)分析证实了共聚物PEO-PPO-PEO包裹在CoFeAu纳米颗粒表面,X射线衍射仪(XRD)测试得出该纳米粒子是面心立方晶体结构、晶格参数为0.406nm、结晶性能好.紫外可见近红外分光光度计吸收光谱仪和振动样品磁强计(VSM)测试证明了该纳米粒子兼具良好的光学和磁学特性.该多功能CoFeAu纳米粒子有望在催化材料、磁材料、光电和生物医药等方面发挥有益作用.
Polyol synthesis method was used to synthesize triblock copolymers with PEO-PPO-PEO triblock copolymer as surfactant and with 1,2-hexadecanediol as reductant, cobalt (Ⅱ) acetylacetonate, iron (Ⅱ) acetylacetonate and acetic acid Gold was used as precursor to synthesize CoFeAu nanoparticles successfully. Fourier transform infrared spectroscopy (FT-IR) analysis confirmed that the copolymer PEO-PPO-PEO was coated on the surface of CoFeAu nanoparticles. The results of X-ray diffractometry The particle is a face-centered cubic crystal structure, with a lattice parameter of 0.406 nm and good crystallization performance. The UV-Vis NIR spectrophotometer and vibrating sample magnetometer (VSM) test show that the nanoparticles have good optical and magnetic properties Learn the multi-functional CoFeAu nanoparticles are expected to play a beneficial role in catalytic materials, magnetic materials, optoelectronics and biomedicine.
