Abstract

By using sol-gel method

Zn and Cu co-doped TiO

:SnO

gel was prepared and coated on glass substrates by spin coating method. Under the same experimental conditions

the effects of the different doped proportion of Zn and Cu and calcined temperature on the structure

morphology and property of Zn and Cu co-doped TiO

:SnO

film were discussed. By using XRD

FTIR

FESEM

etc.

Zn and Cu co-doped TiO

:SnO

film was characterized and its photocatalytic degradation performance on methyl orange was researched. The results demonstrate that the particles of Zn and Cu co-doped TiO

:SnO

film calcined at 600℃ have high crystallization and small size

and the surface is smooth and no obvious cracks. The absorbance of the film is very high in the visible and ultraviolet region. The degradation experiments under UV light illustrate that the photocatalysis degradation efficiency of the film on methyl orange increases greatly compare with pure TiO

film

and the degradation rate reaches the highest with the molar ratio of

(Ti):

(Sn):

(Zn):

(Cu)=10:3:1:1.
