Abstract

Tin silicate glass without SnOx nanoparticles (SiO2·SnOx), a silica glass containing only SnOx nanoparticles (SiO2·SnOxNP) and the improved product, which combines the tin silicate glass with SnOx nanoparticles (SiO2·SnOx·SnOxNP) was prepared. For the structural analysis 119Sn Mössbauer spectroscopy and X-ray diffraction were applied. The 119Sn Mössbauer spectra showed that the SiO2·SnOx·SnOxNP sample had the largest SnII content (12.0%). It also had an outstanding methylene blue degradation with the first-order rate value with (18 ± 2) × 10−3 min−1 with visible light irradiation.
