低温合成单分散性的纳米铁粉末

Preparation of monodisperse iron nanoparticles at low temperature

    摘要
  • 摘要: 采用煤油做试剂、在160~180℃的热分解反应温度下,通过羰基铁的热分解合成单分散性的铁纳米粉末.合成的纳米铁微粒随着反应初始物羰基铁的浓度从0.296mol/L(加入量3.6mL)增加到0.444mol/L(加入量5.4mL)时,其平均尺寸从11.2nm减小到8.6nm,而且它们的形状都是球形.合成的纳米铁微粒通过高分辨率的电子显微镜显示出无定形结构,其表面很容易氧化成尖晶石的四氧化三铁结构.

     

    Abstract: Monodisperse iron nanoparticles were prepared by thermal decomposition of iron carbonyl at low temperatures of 160-180℃ in kerosene.The synthesized iron nanoparticles were spherical and their average size decreased from 11.2 to 8.6 nm as increasing the initial concentration of iron carbonyl from 0.296 to 0.444 mol/L.The synthesized iron nanoparticles are amorphous,but the surface of the particles is easily oxidized and is spinel structure iron oxide by HRTEM.
