Direct dye wastewater photocatalysis using immobilized titanium dioxide on fixed substrate.

Photocatalysis is a promising technology that can be applied to the dyeing of wastewater. During the process of photocatalysis, titanium dioxide (TiO) is often used as a catalyst due to its low cost and broad availability. However, the use of TiO powders can result in certain difficulties associated with separating TiO from the treated wastewater.
