  • 摘要: 钼酸锰纳米材料在光电、催化、磁、机械领域具有重要的应用,现有研究显示其性能与形貌和尺寸具有显著的关系,因此研究纳米钼酸锰生长过程的规律和特征及对生长参数进行定量表征为实现可控合成满足特定需要具有重要的科学意义。但目前已经发展的研究纳米材料的生长过程技术方法,鲜有用通常的生长参数描述纳米材料生长过程的瞬时变化动态精细信息获取其生长的规律和特征。本文采用微量热技术获取了单微乳液法合成不同形貌尺寸MnMoO4纳米材料原位生长过程的特征热谱,结合FE-SEM技术探讨了不同反应参数对MnMoO4纳米材料形貌尺寸及原位生长过程热动力学行为的影响规律,利用热动力学方程获取了生长参数,并且与形貌进行关联,进一步诠释纳米材料的形成机理,最终为发展纳米材料的可控生长提供有力的科学依据。

     

    Abstract: Molybdate material play in great important role in Photoelectric, catalysis, magnetic, mechanical field and have a significant relationship with size and Morphology. Study for quantitative?characteristics and regularity in growth process of nanomaterials is important subject to realized specifics controllable synthesis. But now the technology method is difficulties?to obtain the usually growth parameters to describe the nanomaterials growth process laws and features of instantaneous change dynamic information acquisition. In this paper we use microcalorimetric technique obtained the different morphology and size MnMoO4 in situ growth process thermal spectrum of single microemulsion systems, Combining with the FE - SEM technology to study the different reaction parameters corresponding the MnMoO4 nanomaterials shape size and the influence law of thermal dynamic behavior of in situ growth process. Further, basis of thermal dynamics equations to obtain the growth parameters and associated with morphology, clarifying the formation mechanism of nanometer materials, for the development of controllable growth of nanomaterials to provide powerful science basis.
