  • Preparation and characterization of SnO2 doped TiO2 nanoparticles_ Effect of phase changes on the photocatalytic and catalytic activity.pdf.jpg
  • Article


  • Authors: Hassan, Shawky M.; Ahmed, Awad I.; Mannaa, Mohammed A. (2019)

  • The effects of phase changes on the photocatalytic and catalytic activities of SnO2/TiO2 nanoparticles prepared via surfactant-assisted sol-gel method were investigated. The as-prepared SnO2/TiO2 was calcined at 400 , 500 , 600 , and 700 C. The prepared samples were studied by XRD, TEM, SEM, FTIR, BET, UV-vis diffuse reflection spectroscopy (DRS) and Photoluminescence (PL) spectra. The results showed that the crystallite size and anatase-to-rutile phase transformation increase greatly with increasing the calcination temperature. The transformation of anatase to rutile phase was found to be between 400 and 600 C, and then the anatase completely transformed to rutile phase at 700 C....
