In this work, Tin Oxide (SnO) nanoparticles (NPs) were prepared by green microwave followed by hydrothermal methods, using tea extract as a reducing agent. To verify the stability of physical and chemical properties of SnO NPs, samples were subjected to shock impulsion experimentation. Different characterization techniques were employed to analyze the crystallinity, molecular structure, and optical parameters of the control SnO and shock wave exposed SnO NPs. Powder X-ray diffraction (PXRD) revealed no significant change in crystal structure. Williamson - Hall analysis demonstrates that the stress and strain between Sn-O changes during the impulsion of shocks. Rietveld analysis reveals change in the bond length between Sn-O. The molecular structure is not affected during shock loading, but the optical properties do change. From the photocatalytic experiment, we find that the parameters such as stress, strain, and bond length make an enormous impact in photocatalytic application.
在本研究中，采用绿色微波法并结合水热法，以茶提取物作为还原剂制备了氧化锡（SnO）纳米颗粒（NPs）。为验证SnO NPs物理和化学性质的稳定性，对样品进行了冲击脉冲实验。采用不同的表征技术分析了未受冲击波作用的对照SnO NPs和受冲击波作用的SnO NPs的结晶度、分子结构及光学参数。粉末X射线衍射（PXRD）结果表明晶体结构无显著变化。威廉姆森-霍尔分析表明，在冲击脉冲作用期间，Sn-O之间的应力和应变发生了变化。里特韦尔德分析揭示了Sn-O之间键长的变化。分子结构在冲击加载过程中未受影响，但光学性质确实发生了变化。通过光催化实验，我们发现应力、应变和键长等参数对光催化应用有巨大影响。
