Recent Overview on the Abatement of Pesticide Residues in Water by Photocatalytic Treatment Using TiO2
TL;DR: In this paper, the authors provide an overview of the recent research being developed to photodegrade pesticide residues in water using TiO 2 as photocatalyst, which is the most popular semiconductor material because of its photochemical stability, commercial availability, non-toxic nature and low cost, high photoactivity, ease of preparation in the laboratory, possibility of doping with metals and non-metals and coating on solid support.

Hydrogen generation by irradiation of commercial CuO + TiO2 mixtures at solar pilot plant scale and in presence of organic electron donors
M. I. Maldonado,Enrico Mendes Saggioro,José Peral,Enrique Rodríguez-Castellón,José Jiménez-Jiménez,Sixto Malato +5 more
TL;DR: In this paper, a CuO+TiO2 mixture, based on two commercial and well characterized CuO and TiO2 photocatalyst, was used to produce hydrogen by solar light irradiation and in presence of different organic compounds (methanol, glycerol, formic acid, and the components of a wastewater coming from the biodiesel industry) acting as sacrificial electron donors.

Sulfonamides photoassisted oxidation treatments catalyzed by ilmenite.
TL;DR: The degradation route under CWPO-Photoassisted process displayed a mechanism based on the hydroxylation that led to lower molecular weight intermediates, while under photocatalysis conditions, the appearance of higher molecular Weight intermediates due to organic radical recombination indicates the prevailing of a condensation mechanism.

TiO2 photocatalysis and related surface phenomena
TL;DR: The field of photocatalysis can be traced back more than 80 years to early observations of the chalking of titania-based paints and to studies of the darkening of metal oxides in contact with organic compounds in sunlight as discussed by the authors.
