Nano TiO (titanium dioxide)2Process for degrading dye wastewater by using photocatalyst |
abstract |
The invention discloses a treatment process for photocatalytic degradation of dye wastewater, which adopts K, Ce co-doped TiO as a visible-light catalyst 2 A photocatalyst. The catalyst is prepared into partial K-doped potassium titanate through ion exchange, and then is further subjected to hydrothermal ion exchange to prepare Ce and K co-doped TiO 2 A photocatalyst. The invention solves the problem of low degradation efficiency of dye wastewater in the prior art, and is suitable for degrading organic dye in polluted water. |
