Anatase TiO 2 as a promising photocatalyst has been widely employed in the decontamination treatment of polluted water, air purification and water splitting. Coupling TiO 2 with other semiconductor materials could further enhance the photocatalytic activity. Here, we successfully synthesized the SnO 2 /TiO 2 catalyst by depositing SnO 2 particles on the anatase TiO 2 {105} facets through a gas phase oxidation process. The SnO 2 /TiO 2 catalyst shows higher photocatalytic activity for decomposition of MB than that of the pure TiO 2 catalyst. The enhanced photocatalytic activity can be attributed to the efficient charge separation since TiO 2 and SnO 2 catalyst have staggered energy level.
