Facile Preparation of Nanoporous SnO2 for Application in Photodegradation of Methylene Blue
Nanoporous SnO2 with high photocatalytic activity has been successfully prepared by a photochemical method, using SnCl2 aqueous solution as a precursor. The as-synthesized sample was characterized by XRD, N2 adsorption-desorption and UV-vis. The photocatalytic activity of the sample was evaluated by degrading methylene blue (MB) aqueous solution under the UV light source and was compared with that of the commercial titania (Degussa P25). The results showed that the produced SnO2 can degrade MB solution quickly and has comparative photocatalytic performance with P25 for degrading MB. This facile method supplies an effective way to prepare SnO2 photocatalyst.
