Amorphous MoS2 spheres with diameters ranging from 150 nm to 1.5 μm are successfully prepared following a reliable one-pot hydrothermal route using a homemade autoclave and inexpensive reactants, at a low temperature (160 °C) and a short reaction time (12 h). The obtained material is comprehensively characterized by X-ray diffraction, scanning-electron microscopy, energy-dispersive X-ray spectroscopy, atomic force microscopy, and infrared spectroscopy. The X-ray diffraction pattern reveals the amorphous structure of the prepared sample without stacking layers, whereas scanning-electron microscopy and atomic force microscopy images indicate the formation of spheres with regular shape and morphology.

无定形二硫化钼球体的亚临界水热合成

使用自制高压釜和廉价反应物，在低温 (160 °C) 和短反应时间 (12 h) 下，通过可靠的一锅水热法成功制备了直径范围为 150 nm 至 1.5 μm 的无定形 MoS2 球体。所得材料通过X射线衍射、扫描电子显微镜、能量色散X射线光谱、原子力显微镜和红外光谱进行了综合表征。X 射线衍射图显示所制备样品的无定形结构没有堆叠层，而扫描电子显微镜和原子力显微镜图像表明形成了具有规则形状和形态的球体。
