Abstract:
The Inorganic Fullerene-like MoS2 was obtained by a simple precipitation method using the polyethylenegly colas the dispersant, The hydroxylamine hydrochloride as the reductant, and (NH4)2S as the sulfursource. Themorphology and structure of the product were characterized by Powder X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and High-resolution Transmission Electron Microscopy (HRTEM). The results suggest that the polyethylene glycol dispersant can be adsorbed on the particle surface of the reaction precursor, amorphous MoS2 powders, to form a relative isolated environment. This isolated environment may induce an obstruct effect which helps the precursor nano-particles transfer to the IF structure in the subsequent calcinations process.

摘要:
采用简单的沉淀法,利用聚乙二醇作为分散剂,盐酸羟铵为还原剂,以硫化铵为硫源合成了具有无机类富勒烯结构的纳米二硫化钼,通过粉末X射线衍射(XRD)、扫描电镜(SEM)和高分辨透射电镜(HRTEM)等方法对其形貌和结构进行了表征.结果表明,用聚乙二醇做分散剂,使其吸附在前驱物表面使颗粒环境呈现出一个相对隔绝的状态,在煅烧过程中,其空间位阻作用有利于MoS2纳米颗粒形成无机类富勒烯结构.
