The results show that the crystalline phase of erbium... with an appropriate content, which is attributed to increasing the content of surface oxygen vacancies and defects. The higher the FS intensity, the higher the photocatalytic activity. The photocatalytic degradation......
as photocatalysts were carried out to investigate the photocatalytic activity of ZnO/TiO2-NTs. The photocatalytic mechanism for ZnO/TiO2-NTs with high photocatalytic activity was proposed. The results show that the ZnO/TiO2-NT with molar ratio of Zn to Ti of 1?4 exhibits excellent photocatalytic activity for photodegradation of methyl orange. The enhanced photocatalytic activities for ZnO/TiO2-NTs own......

, was prepared using a novel method and its photocatalytic activity on the photodegradation of acridine dye in aqueous solution was tested. By this method, the crystal form and grain size of the immobilized TiO2 were well maintained. Compared with TiO2 powder, the photocatalytic activity of TiO2/PS thin films was not significantly reduced. The catalyst is stable and can be reused several times without......
