本论文尝试使用微乳液辅助水热合成技术制备锌、铜、银的钼酸盐低维纳米结构材料。通过改变实验条件控制合成了不同尺寸及不同形貌的纳米结构。主要研究了 w值、反应物浓度、反应温度对产物尺寸和形貌的影响，对生成的几种低维纳米结构的形成机理做了探索。对于锌的钼酸盐，在反应物浓度比较低时，随着w值增大该产物由片状体自组装成花状的微米结构，然后变为块状晶体。而反应物浓度增大后，w值不同主要对产物尺寸的影响，w值大的尺寸大。对于铜的钼酸盐，增大反应物浓度，适当降低反应温度能使钼酸铜纳米棒的直径减小。减小w值，减小反应物浓度或适当降低反应温度都能使产物钼酸银纳 米球的直径减小。

The present dissertation attempt using microemulsion assisted hydrothermal synthesis for preparation of zinc, copper, and silver molybdate low dimensional nanostructure material. Nanostructure with different size and dif ferent morphology were synthesized through changing experimental condition. We mainly has studied the value of w, the reactant consistence, reaction temperature, which affect the size and the morphology of the as- synthesized product, and theformation mechanism of the nanostructure materials was speculated. Regarding the zinc molybdate, when the reactant consistence is low, the products assemble by the nanosheets and form the flower-like micro-structure, and then become the massive microcrystals with increase of the w value. But when the reactant consistence increases, the w value mainly influence the size of the products, the size increases along with the increase of the w value. For the copper molybdate, if the reactant consistence increases, suitable decrease of the reaction temperature can make the diameter of the nanorod reduce. The diameter of Ag2MoO4 nanospheres we obtained becomes small through reducing the reaction tempreture, the w value or the reactant consistence.
