Zn-Ti-O/FTO 复合薄膜的选择降解

Abstract

Abstract:

The Zn-Ti-O composite film prepared from fluorine-doped tin oxide (FTO) conducting glass with sol-gel technology has been investigated, whose phase structures analyzed by X-ray diffraction (XRD), absorption spectra measured by UV-Vis spectrophotometer, and morphologies characterized by scanning electron microscope (SEM). The photocatalytic reaction of Zn-Ti-O/FTO has been tested by ultraviolet light with wavelength of 255 nm as light source to methyl orange (MO), methylene blue (MB) and rhodamine B (RhB), respectively. Results indicate that the Zn-Ti-O film prepared on FTO substrate shows obvious preference for degradation of organic compounds---the optimal degradation of MB is 90.3%/(6 h). This preference may be related to the relative positions of the bottom of conduction band/the top of valence band of film and substrate, and the lowest unoccupied molecular orbital/highest occupied molecular orbital of the organic degradation.

Key words: Zn-Ti-O/FTO, photocatalysis, preference, sol-gel
