Synthesis of nanocrystalline MoSe2 by sonochemical reaction of Se with Mo(CO)6

Nanocrystalline MoSe2 was prepared by a sonochemical reaction between Mo(CO)6 and Se in decalin at 273 K in nitrogen atmosphere. The products were characterized by X-ray powder diffraction (XRD), transmission electron microscope (TEM), energy-dispersive X-ray spectroscopy (EDXS) and thermal analysis (TG and DSC). The XRD patterns showed that the product is amorphous, while annealing at 330 °C yields nanocrystalline MoSe2. The influence of ultrasound and temperature is discussed.
