3D mesoporous CuFe2O4 as a catalyst for photo-Fenton removal of sulfonamide antibiotics at near neutral pH.
TL;DR: Mesoporous copper ferric has good circulation, which indicates that it may have excellent application in the field of photo-Fenton, and hydroxyl radical is proved to be the main active free radical based on EPR.

TL;DR: Estrogenicity assays showed that methyl paraben was more estrogenic than EP; however, parabens are slightly estrogenic compared to 17β-estradiol, and liquid chromatography-time of flight mass spectrometry revealed the formation of methylParaben, 4-hydroxybenzoic acid, benzoic Acid and phenol as primary transformation by-products.

TL;DR: The photocatalytic degradation of a mixture of three compounds spiked in secondary treated wastewater by means of simulated solar radiation over titania suspensions was investigated in this paper, where Bisphenol-A (BPA) and 17α-ethynylestradiol (EE2) were chosen as representatives of emerging micro-contaminants, while phenol was chosen as a reference contaminant.

Visible-Light Photocatalysis in Nitrogen-Doped Titanium Oxides
TL;DR: Film and powders of TiO2-x Nx have revealed an improvement over titanium dioxide (TiO2) under visible light in optical absorption and photocatalytic activity such as photodegradations of methylene blue and gaseous acetaldehyde and hydrophilicity of the film surface.

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.
