Effect of ion (Al, Fe and Zn) co-doped TiO2 nanotubes on photocatalytic degradation of humic acids under UV/ozonation for drinking water purification
O3/UV/TiO2 was used to effectively decompose humic acids (HAs) in drinking water. A series of Al-doped, Fe-doped, Zn-doped and co-doped TiO2 nanotubes were successfully synthesized by a hydrothermal method. According to the characterization of ion-doped TiO2 nanotubes, Al3+ and Fe3+ ions occupied substitutional positions in the crystal lattice, and Zn2+ ions were partially dispersed in the ...
