Abstract

Four kinds of Bi ₂ WO ₆ with different morphology were prepared by facile hydrothermal method with different additives and pH. In the photocatalytic degradation of gaseous toluene under visible light irradiation (λ > 420 nm), the nest-like Bi ₂ WO ₆ performed the best photodegradation efficiency of 100% in only 20 min, and could be reused for at least eight times without a significant loss of catalytic activity. According to the characterization techniques, including XRD, SEM, TEM, XPS, BET, UV–vis, PL and TPR, the excellent photocatalytic activity of the nest-like Bi ₂ WO ₆ is ascribed to the small particle size, large photo response interval, narrow band gap, high separation efficiency of electron-hole pairs and low recombination rate of photogenerated electron holes, that result in abundant reaction active sites.
