Photocatalytic efficiency and infrared spectra characteristics of ZnFe2O4 and doped ZnFe2O4 films on glass surface |

| Abstract: | Three kinds of films on glass substrate are prepared with the sol-gel method, including TiO 2 films, doped ZnFe 2O 4 TiO 2 films, and ZnFe 2O 4 films. To analyze the properties of films by using ultraviolet spectrum and infrared spectrum, we find the extreme wave-length, photocatalytic efficiency, and infrared spectrum. It indicates that ZnFe 2O 4 films and TiO 2 films doped with ZnFe 2O 4 are superior in photocatalytic degeneration properties, with increased absorptivity for infrared. |
