Abstract

The cobalt-promoted MoS₂ microspheres have been synthesized by hydrothermal methods using sodium molybdate precursors. Scanning electron microscopy indicates that spherical shape morphology and cobalt atoms are detected at MoS₂ edges corresponding to (101)-plane as revealed by Cs-corrected transmission electron microscopy. The magnetic states were measured by magnetization curves obtaining a 0.044 emu/g due to paramagnetic contribution. Furthermore, the electronic structure from the density of states for 2H-MoS₂ with and without cobalt at the (101) edge plane possesses a magnetic property with a value of 0.16 μ_B attributed to broken symmetry.

钴促进的 MoS2 微球中的磁态

利用钼酸钠前驱体，通过水热法合成了钴促进的 MoS2 微球。扫描电子显微镜显示出球形形态，铯校正透射电子显微镜显示在对应于（101）面的 MoS2 边缘检测到钴原子。通过磁化曲线测量磁态，得出顺磁贡献为 0.044 emu/g。此外，从 2H-MoS2 的状态密度（在 (101) 边缘平面有钴和没有钴）得出的电子结构具有磁性，其值为 0.16 μB，这归因于对称性被打破。
