| Abstract: | In order to improve the photodegradation of TiO2 and reduce environmental pollutants by using light energy,TiO2 photocatalyst modified by doping was studied in this paper.La-doped TiO2 composite films were prepared by adding lanthanum nitrate into the mixed solution of ammonium fluotitanate and boric acid and by liquid phase deposition(LPD) method.The composition,structure,and surface form of titanium dioxide thin films were studied in XRD,UV-Vis,XPS,and SEM means,and the photocatalytic activity of the thin... |
