A study of the structural, morphological, and optical properties of shock treated SnO(2) nanoparticles: removal of Victoria blue dye

In this work, Tin Oxide (SnO(2)) 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(2) 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(2) and shock wave exposed SnO(2) 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.
