| 摘要: |
| 采用液相沉淀-高温氢还原两步合成新方法制备单分散球形MoS2超细粉体材料,利用透射能谱、X射线衍射仪(XRD)、冷场扫描电子显微镜(SEM)和马尔文激光粒度仪等研究了反应条件对产物化学组成、晶型的影响以及酸浓度、熟化时间和反应温度对前驱体MoS3平均粒径的影响.研究结果表明:反应条件对前驱体MoS3的晶型没有影响;MoS2的结晶度随氢还原温度的升高而逐步提高;MoS3的平均粒径随酸浓度、熟化时间及反应温度的升高而增加. |

| Abstract: |
| Mono-dispersed spherical MoS2 ultra-fine power materials were synthesized by a new two-step,liquid precipitation and hydrogen reduction synthetic method.Using Transmission energy spectrum,Powder X-ray diffraction(XRD),Scanning Electron Microscope(SEM) and Mastersizer 2000 Laser Particle Size Analyzer,the chemical composition and crystalline of products and the effects of different liquid precipitation reaction conditions,such as acid concentration,aging time and reaction temperature,on the average particle size of precursor MoS3 were studied,respectively.The results show that the changing of liquid precipitation reaction conditions have no effect on the crystalline of precursor MoS3,the crystalline of MoS2 increased while the hydrogen reduction temperature increased,the increasing of acid concentration,aging time and reaction temperature would lead to the increase of the average particle size of MoS3,respectively. |
