The flower-sphere molybdenum disulfide has been synthesized by reaction of Na2MoO4 and CS(NH2)2 with NH2OH·HCl or H2C2O4 as reductant. The microstructure and chemical composition of the product were characterized by means of X-ray diffraction and scanning electron microscope. XRD patterns showed that the molar ratio of Mo to S had a great effect on the purity of the product. When the molar ratio of Mo to S was 1:5, the product was nearly pure MoS2. SEM images showed that the particle size increased as the molar ratio of Mo to S reduced. The MoS2 microspheres had rough surfaces and were constructed with sheet-like structures in the two systems. But the product from the system of NH2OH·HCl as reductant has the bigger particle size, clearer petal-sheets, coarser surface and weaker agglomeration than that from the system H2C2O4 as reductant. The possible chemical reactions in hydrothermal systems were preliminarily discussed.
