One-step hydrothermal synthesis of MoS2 nano-flowers with high surface area and crystalline
One-step and controlled pH hydrothermal synthesis of transition metal disulfide using double molybdenum sources to synthesize MoS2 nano-flowers at low temperature was first reported.Anhydrous molybdenum pentachloride (MoCl5) and four sulfur ammonium molybdate ((NH4) 6Mo7O24·4H2O) were the molybdenum source and CS (NH2) 2 was the sulfur source.Through hydrothermal method,MoS2 was obtained at 180 ℃.The pH value of system was controlled by adjusting the molar ratio of MoCl5 and (NH4) 6Mo7O24·4H2O.The products were characterized by powder X-ray diffraction (XRD),scanning electron microscopy (SEM),surface area (BET) and transmission electron microscopy (TEM).The results show that the products were hexagonal MoS2 with a high crystalline and flower-like structure consisted of small particles.The thickness of petals is a few to tens ofnanometers.By changing the molar ratio of molybdenum sources,the resultant phase from the mixed phase transited to the pure phase and the purity of synthetic MoS2 crystal increaseed.
