采用正金刚烷甲酸和三烷基膦作为稳定剂，通过乙酰丙酮钯的多元醇还原和五羰基铁的热分解制备了单分散FePd纳米颗粒。通过控制稳定剂的浓度和类型以及反应条件，可以将平均粒径调节为 11 至 16 nm。 FePd 纳米颗粒的高单分散性导致形成由六方密堆积颗粒组成的二维 (2D) 超晶格，这一点通过 X 射线衍射图和高分辨率透射电子显微镜 (HRTEM) 图像得到证实。该路线为研究纳米 FePd 材料的磁性能提供了一个有前途的候选路线。
Monodisperse FePd nanoparticles were prepared by polyol reduction of palladium acetylacetonate and thermal decomposition of iron pentacarbonyl, using a combination of n-adamantanecarboxylic acid and tri-alkylphosphine as stabilizers. The mean particle size can be tuned from 11 to 16 nm by controlling the concentration and type of stabilizers and reaction conditions. High monodispersity of FePd nanoparticles leads to the formation of two-dimensional (2D) superlattices consisting of hexagonal close-packed particles, which was confirmed by X-ray diffraction pattern and high-resolution transmission electron microscopic (HRTEM) images. This route provides a promising candidate for studying the magnetic properties of nanosized FePd materials.
