| Abstract: | Physical and photocatalytic properties of lanthanum-doped nanocrystalline titania were investigated, as well as their relationship. Photocatalytic activity was tested via photocatalytic decomposition of methyl orange and butylrhodamine-B. The results showed that doping of lanthanum enhanced the photocatalytic activity of titania, and titania doped with 0.02% mole fraction of lanthanum exhibited the best activity. The catalyst is applicable to treatment of printing and dyeing wastewater. |
