Article Preview

Nanocrystalline tin oxide (S1) was prepared by using molten boric acid as a flux and was characterized by XRD, TEM, and BET analysis. Its photocatalytic activity under UV excitation was evaluated by the photodegradation of methylene blue in water and compared to that of the well-known P25 (TiO2) and SnO2 powder (S2) synthesized from hydrothermal system without the participation of H3BO3. It has been revealed that S1 exhibits similar photocatalytic activity to that of P25 powder and better than that of S2. The high photocatalytic activity of S1 is most likely to be originated from its small particle size and the boron-doping in the crystal lattice.
