Photocatalysis in water environments using artificial and solar light
TL;DR: A review of the work done on photocatalytic reactions can be found in this paper, where the authors focus on two main themes: (i) light absorption evaluation when artificial light is used and (ii) description of reactor configurations and applications when solar radiation is employed.

Large-scale preparation of ordered titania nanorods with enhanced photocatalytic activity.
TL;DR: The as-deposited titania nanorods exhibited extremely high initial photocatalytic activity but declined to a poor value after the consumption of beneficial oxidative peroxo complexes coordinated to Ti(IV).

Titanium dioxide sol–gel deposited over glass and its application as a photocatalyst for water decontamination
TL;DR: In this paper, anatase thin films were used as an efficient form of deposited TiO 2 for the photocatalytic degradation of 4-chlorophenol, a priority pollutant commonly used as a model in photocatalysis, and for carbaryl, a carbamic pesticide.

Photocatalytic degradation of organic water contaminants: Mechanisms involving hydroxyl radical attack
Craig S. Turchi,David F. Ollis +1 more
TL;DR: In this article, it is proposed that the hydroxyl radical, OH·, is the primary oxidant in the photocatalytic system and four possible mechanisms are suggested, all based on OH· attack of the organic reactant.
