摘要
采用微量热技术研究了单微乳液法合成不同形貌尺寸MnMoO_4纳米材料原位生长过程的特征热谱,结合FESEM技术探讨了不同反应参数对MnMoO_4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.
Microcalorimetric technique was applied to stiudy the thermal spectra for the in-situ progress of nano MnMoO_4( with different mophology and size) prepared in single microemulsion system. Combining with the FESEM technology,the influences of different reaction parameters on the shape,size,and thermal dynamic behavior of MnMoO_4 nanomaterials were investigated. The formation mechanism of the nanometer materials was explored by the growth parameters obtained from the thermal dynamic equations and associated morphology. The work provides scientific basis for the development of controllable growth of nanomaterials.
