A technology has been developed for the formation of nanoparticles of molybdenum and tungsten disulfides solid solutions by aerosol assisted chemical deposition from the gas phase. Unlike conventional methods of such solid solutions formation by oxides sulfurization methods, this technology allows to obtain nanoparticles in a gas flow with a high speed and the ability to control the composition and particle size. Single-source precursors ammonium thiomolybdate and thiotungstate are used, their ratio defines metals ratio in nanoparticles. Particles size control is available via concentration variation of initial solution. It was experimentally shown with TEM, XRD and Raman spectroscopy that nanoparticles are true solid solutions. Metal atoms are uniformly distributed between sulfur layers.

已经开发了一种技术，该技术通过从气相通过气溶胶辅助化学沉积形成钼和二硫化钨固溶体的纳米颗粒。与通过氧化物硫化方法形成这种固溶体的常规方法不同，该技术允许以高速且具有控制组成和粒径的能力在气流中获得纳米颗粒。使用单源前体硫代钼酸铵和硫钨酸铵，它们的比例定义了纳米粒子中的金属比例。可以通过初始溶液的浓度变化来控制粒度。通过TEM，XRD和拉曼光谱法实验证明，纳米颗粒是真正的固溶体。金属原子均匀地分布在硫层之间。
