Low temperature decomposition of PCDD/PCDF, chlorobenzenes and PAHs by TiO2-based V2O5–WO3 catalysts
TL;DR: In this article, the oxidation of representative congeners of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorined dibenzofurans (PCDFs) was investigated on two commercial V2O5-WO3/TiO2-based catalysts, optimized for the combined reduction of nitrogen oxides and decomposition of dioxins.

Aniline degradation by combined photocatalysis and ozonation
TL;DR: In this article, the combination of TiO 2 -assisted photocatalysis and ozonation in the degradation of aniline in aqueous solution was investigated. And the results showed that the ozonization pretreatment followed by photocata-alysis strongly increased the yield of TOC removal in comparison to either ozoning or photocatalysing separately.
