Abstract

Abstract

This paper used the sol-gel method to prepare Fe³⁺ doped GO-TiO₂ films with different proportions on glass substrates. The samples were characterized by X-ray diffraction (XRD) and ultraviolet-visible spectrometer (UV-Vis). The photocatalytic degradation of TCM was irradiated under a UV lamp with a power of 20 W and wavelength of 254 nm for 210 min to investigate the effects of Fe³⁺ doping ratio, film calcination temperature, film layers, and film reuse times on the degradation. The results show that the samples are anatase, and the doping of Fe³⁺ reduces the crystal size, and a redshift occurs. The degradation effect of TCM increases with the increase of Fe³⁺ doping ratio, and the film formed by calcination at 400 ℃ is the best. Whether Fe³⁺ is doped or not, multiple coating can improve the degradation rate of TCM. The degradation ability of each film tends to be stable after being reused four times.
