Abstract

In this study HPWO·9HO and HPMoO·6HO (HPA) particles were changed into nano forms by heat-treatment in an autoclave as a simple, repaid, inexpensive and one step method. The particle size of these nanoparticles was around 25 nm. The as-synthesized nanostructures were characterized by dynamic light scattering, X-ray powder diffraction, transmission electron microscopy, Fourier transform infrared spectroscopy and inductively coupled plasma analyzer. Thermal stability of nanoparticles was surveyed by thermal gravimeter analyse. Acidity of prepared nanoparticles was investigated by pyridine adsorption method. Results showed rising acidity by declining particle size of HPA.

摘要

在本研究中，通过在高压釜中进行热处理，以一种简单、快速、廉价的一步法将HPWO·9H₂O和HPMoO·6H₂O（HPA）颗粒转变为纳米形式。这些纳米颗粒的粒径约为25纳米。通过动态光散射、X射线粉末衍射、透射电子显微镜、傅里叶变换红外光谱和电感耦合等离子体分析仪对合成的纳米结构进行了表征。通过热重分析仪研究了纳米颗粒的热稳定性。采用吡啶吸附法研究了制备的纳米颗粒的酸度。结果表明，随着HPA粒径的减小，酸度增加。
