Abstract

Carbon dioxide laser synthesis from gaseous precursor has been successfully applied to produce nanosized MoS2particles. Molybdenum hexacarbonyl [Mo(CO)6] and hydrogen sulphide were used as gas phase reactants. A detailed x-ray diffraction analysis of the as-synthesised powder confirmed the nanosize character of the MoS2powder (x ray size ∼3 nm) and showed that the particle structure could be described as a turbostratically stacked layered system. After thermal treatment at 1000°C the powder underwent a restacking and ordering process. The x-ray reflection intensities and the line profile analysis of the (00l) diffraction lines showed the retaining of turbostratic desorder and the apperance of"paracrystalline" distortions in the MoS2sandwich layers with an average fluctuation parameter of g= 0.02.
