Fenton-based electrochemical degradation of metolachlor in aqueous solution by means of BDD and Pt electrodes: influencing factors and reaction pathways.
Abdoulaye Thiam,Ricardo Salazar +1 more
TL;DR: This work explores the role of electrode material and the oxidation ability of electrochemical advanced oxidation processes (EAOPs), such as electro-oxidation with or without H2O2 production, electro-Fenton (EF), and UVA photoelectron- Fenton (PEF), in the degradation of metolachlor.
Journal ArticleDOI
Evaluation of acute toxicity and teratogenic effects of disinfectants by Daphnia magna embryo assay.
TL;DR: The study concluded that the acute toxicity of the three disinfectants to young daphnids and embryos were hypochlorite, formaldehyde, and m-cresol, and the effects on growth mostly occurred in the late stages of organogenesis.
Journal ArticleDOI
Photocatalytic decomposition of cortisone acetate in aqueous solution.
TL;DR: The decomposition reaction was found to be pseudo-first order and the rate constant decreased as a function of increasing initial CA concentration, and the highest photocatalytic degradation rate constant was obtained combining both TiO2 P25 and S2O8(2-) (0.071 min(-1)) showing a synergistic effect.

Matthias Schmidt,Ana M. Cubillas,Nicola Taccardi,Tijmen G. Euser,Till Cremer,Florian Maier,Hans-Peter Steinrück,Philip St. J. Russell,Peter Wasserscheid,Bastian J. M. Etzold +9 more
TL;DR: The use of photonic crystal fibers in chemistry and sensing is reviewed and recent applications as catalytic microreactors are presented in this article, where results on homogeneous catalysis and the immobilization of homogeneous and heterogeneous catalysts in the fiber channels are discussed.
Journal ArticleDOI
Synthesis of Bi2O3/TiO2 nanostructured films for photocatalytic applications
TL;DR: In this article, a 3D growth morphology with high surface area templates for photocatalytic applications was developed by reactive magnetron sputtering, which was adapted to abide a vapour-liquid-solid mechanism.

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.
