Fund Project:

The Zn(Ⅱ) and Cd(Ⅱ) doped nanosize PbTiO₃ powders have been prepared by a sol-gel method from titanium oxyoxalate, citric acid, lead acetate, zine acetate or cadmium oxalate and characterized by XRD and TEM.Their catalytic activities for photocatalytic degradation of reactive turquoise blue K-GL was found to be greater than that of pure PbTiO₃ powder, whereas the PbTiO₃ doped with 5%(mole fraction) of Zn(Ⅱ) and Cd(Ⅱ) showed the greatest catalytic activity.The activity of Zn(Ⅱ) doped PbTiO 3 is higher than that of Cd(Ⅱ) doped one, likely due to the small radius of zinc ion which induced distortion of the lattice.The optimum pH value of the solution for photodegradation appeared less than 10.
