Abstract
The use of semiconducting oxide photocatalyst in contaminant purification has recently drawn significant attention in both materials and environmental science. In this study, the compound SrBi2Nb2O9 with layered perovskite-type structure was synthesized by solid state reaction, and the network microstructure film was fabricated by the aerosol deposition method. The compound powder and aerosol-deposited film with SrBi2Nb2O9 were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Ultra violet–visible (UV–vis) spectrophotometry. The photocatalytic activity of the aerosol-deposited film with SrBi2Nb2O9 was evaluated by photo-induced destruction of Rhodamine B under the irradiation of UV and visible light. The aerosol-deposited film with SrBi2Nb2O9 exhibited higher photocatalytic activity than that of SrBi2Nb2O9 powders. This result is attributed not only to the small sized grain, but also to the existence of a network microstructure capable of supporting the enhanced loading of organic contaminants on the aerosol-deposited film.
