Photocatalytic Activity of Pd Doped Tin Dioxide Inverse Opal Films

Abstract:

Inverse opal films (IOFs) of SnO₂ doped with Pd were prepared by the self-assembly technique using polystyrene microsphere (PS sphere) as template in combination with a sol-gel method. The photocatalysis properties of SnO₂ IOFs were estimated through measuring the rate of the degradation of methylene blue (MB). The result shows that SnO₂ IOFs have good photocatalytic activity, the solution of MB was degradated over 60% in 4 hours when it was dipped in SnO₂ IOFs and exposed in the UV light. The addition of Pd in SnO₂ IOFs improved the photocatalytic activity of the films and the degradation of MB can exceed 80% with the same condition. This sort of SnO₂ IOFs doped with Pd indicated a potential application in photocatalysis field.
