摘　　要：通过水热法合成了平均粒径约300～500am的MoO2亚微米球。辅助剂PEC,400在合成过程中，既作还原剂又作保护剂。探究了产物从MoO3纳米棒向MoO2亚微米球转变的最佳制备条件。采用XRD和SEM手段对产物进行了系统的表征。初步探讨了MoO3纳米棒向MoO2亚微米球转变的机理。The average diameter of the MoO2 sub-microspheres synthesized through controllable hydrothermal method was about 300-500 nm with PEG400 acting both protective and reducing agent during the synthesizing process. Researches had been done on the optimum preparation conditions from MoO3 rods to MoO2 spheres. The final products were analyzed with x-ray diffraction （XRD）and scanning electron microscopy （SEM）.The formation mechanism for rods to spheres transition of molybdenum oxide was also investigated.
