【Abstract】 In this paper study nanometer TiO₂ films doped with rare-earth element La or Ce were prepared by sol-gel process, and photo-catalytic degradation tests were carried out, with methyl orange being the degradation object, to investigate the effect of doping on the photo-catalytic degradation power of the nanometer TiO₂ films. The results obtained show that of the two rare-earth elements doped, the effect of La is better than that of Ce. The results of this study have provided a reliable basis for the practical application of this technology.更多还原
