| 摘 要： | 以CoCl2.6H2O和CH4N2S为前驱物，通过超声喷雾热解法，制备了立方相Co9S8纳米碎壳和Co3S4 纳米晶。所制备的样品用XRD,SEM,EDX和FTIR进行了表征，结果发现过量的硫脲和反应时间对产物的形貌有明显影响。通过控制反应温度可以控制样品的物相，并且对空心和实心晶体结构的产生提出了相应的机理。

| Abstract: | Cubic Co9S8 fracture structure nanoshells and cubic Co3S4 nanocrystallines were prepared by ultrasonic spray pyrolysis process using cobalt chloride (CoCl2?6H2O) and thiourea (CH4N2S) as the starting materials. The as-prepared Co9S8 nanoshells and Co3S4 nanocrystallines were characterized by X-ray diffraction (XRD), Scanning electron microscope (SEM) with energy-disperse X-ray spectroscopy (EDX) attachment and Fourier-transform infrared (FTIR) spectrometer respectively. It was found that the phase transition could be controlled by adjusting the reaction temperature, while morphologies of final products could be influenced by the molar ratio and reaction time of precursor. Meanwhile, possible mechanism for the formation of hollow and solid crystalline structures of the product was proposed. |
