摘　　要：以MoO3和S粉为原料,高纯氩气为载气和反应气氛,在石英管反应器中,用化学气相沉积法制备富勒烯结构MoS2纳米粒子,用XRD对产品的成分进行测量,SEM观察产品的整体微观形貌。结果表明,在900℃下,通氩气1 cm3/min,保温8 h,制备了平均粒径在250 nm左右的高纯富勒烯结构MoS2纳米粒子。Using the powder of MoO3 and S as raw materials,high pure Ar gas as transportation carrier and reaction atmosphere,prepare fullerene-like structure nanoparticles of MoS2 by CVD in reactor of quartz tube in experiment.The elements of products were characterized using XRD;and unitary microcosmic morphology of products were investigated using SEM.The results shows that keeping for 8 h at the temperature of 900 ℃,and injecting Ar gas 1 cm3/min,high pure fullerene-like structure nanoparticles of MoS2 whose average particle size are about 250 nm had been synthesized.
