We have synthesised osmium nanoparticles of defined size (1.5-50 nm) on a B- and S-doped turbostratic graphitic structure by electron-beam irradiation of an organometallic osmium complex encapsulated in self-spreading polymer micelles, and characterised them by transmission electron microscopy (TEM), high-resolution TEM (HRTEM), and atomic force microscopy (AFM) on the same grid. Oxidation of the osmium nanoparticles after exposure to air was detected by X-ray photoelectron spectroscopy (XPS).
我们通过对封装在自蔓延聚合物胶束中的有机金属锇配合物进行电子束辐照,在硼和硫掺杂的涡轮层状石墨结构上合成了尺寸确定(1.5 - 50纳米)的锇纳米颗粒,并在同一网格上通过透射电子显微镜(TEM)、高分辨率TEM(HRTEM)和原子力显微镜(AFM)对其进行了表征。通过X射线光电子能谱(XPS)检测了暴露于空气中后锇纳米颗粒的氧化情况。
