Abstract

The relationship between local structure and visible-light photocatalytic ability of tin silicate glass prepared by sol–gel method was investigated. 119Sn Mössbauer spectrum of SnOx·SiO2 glass prepared from SnCl2 showed a small peak of SnII component besides the major amount of SnIV. The smallest bandgap energy of 2.5 ± 0.5 eV was estimated from Tauc plot, and the largest first order rate constant (k) of (13.8 ± 0.1) 10−3 min−1 was recorded from the methylene blue degradation test under visible-light irradiation. It is concluded that SnII shows remarkable photocatalytic ability when it is incorporated into silica glass matrix.
