Photocatalytic Environmental Remediation of Cassiterite-Titania Nanocomposite

摘要

Nanocrystalline cassiterite(SnO2),titania(TiO2),and cassiterite-titania(SnO2-TiO2)are synthesized by microwave method.X-ray diffraction study reveals that cassiterite properly supported on the surface of titania.Nano sized cassiterite,titania,and cassiterite-titania nanocomposite are confirmed by transmission electron microscopy technique.The particle size of the SnO2,TiO2,and their nanocomposite is in the range of 12-18 nm.The enhanced photocatalytic activity is observed in the SnO2-TiO2 composite as compared to SnO2 and TiO2.
