Abstract

Titanium dioxide is an effective photocatalyst for the breakdown of many environmental contaminants. The complex mixtures that can occur in water matrices can significantly affect the breakdown of the contaminants in water by titanium dioxide (TiO₂). The authors discuss a wide variety of foulants and inhibitors of photocatalytic TiO₂ systems and review different methods that can be effective for their fouling prevention. Approaches to regenerate a fouled or contaminated TiO₂ catalysts are explored and the effect of substrates on immobilized titanium dioxide is also reviewed.
