TL;DR: In this paper, a comparison of their catalyst compositions with literature in this area suggests that the increase in activity due to the addition of silica or zirconia may be a result of higher surface acidity.

TL;DR: In this paper, the authors used titania and platinized (0.1 wt.-%) titania photocatalysts for the degradation of benzene in oxygen-containing gaseous feed streams.

TL;DR: In this paper, the photocatalytic degradation of ethylene in airstreams has been studied over the temperature range 30-110 °C using a packed bed reactor containing sol-gel-derived TiO2 or platinized TiO 2 particulates.

TL;DR: In this article, the results showed that the catalytic and structural properties of the sulfated TiO2 catalysts were greatly improved by sulfation, and the results indicated that surface fluorination of the catalysts during the reaction improved its activity, induced the formation of the fluorinated byproduct CFC-13, and changed such properties as its specific surface area, pore size distribution, and crystal size.

TL;DR: In this article, the photocatalytic degradation of trichloroethylene and tetrachloronitriouethylene in the gas phase, when porous TiO2 pellets were used, produced such undesirable chlorinated byproducts as chloroform (CHCl3) and carbon tetrACHloride (CCl4) and the formation of byproducts was reduced by increasing oxygen mole fractions in the feed gas stream and/or using the TiO 2 pellets fired at a lower temperature.
