| Abstract: | The characterization of PbTiO 3 prepared by hydrothermal method was carried out by means of TEM, XRD, SEM, FTIR and EA. The average particle size of the powder from TEM is 500 nm. The effectiveness of photocatalytic degradation and influence of irradiation time on activity for turquoise blue (KGL) solution in ultraviolet light have been measured. The results show that the activity of this kind of PbTiO 3 is better than that of the others. Experiments reveal that the catalytic activity is also influenced by pH of the solution. |
