TL;DR: In this article, the TiO2/UV photocatalytic degradation of methylene blue (MB) has been investigated in aqueous heterogeneous suspensions, and it has been shown that the degradation pathway can be determined by a careful identification of intermediate products, in particular aromatics, whose successive hydroxylations lead to the aromatic ring opening.

TL;DR: In this article, the photocatalytic degradation of five various dyes has been investigated in TiO 2 /UV aqueous suspensions, and it was shown that the dyes can be degraded by varying the chemical structures, either anthraquinonic (Alizarin S), or azoic (Crocein Orange G (OG), Methyl Red (MR), Congo Red (CR)) or heteropolyaromatic (Methylene Blue (MB)).

TL;DR: The role of adsorption is suggested, indicating that the reaction occurs at the TiO 2 surface and not in the solution as mentioned in this paper, and the presence of a silica-binder with an acidic pzc is suggested to be at the origin of the decrease in efficiency.

TL;DR: An eco-friendly advanced oxidation processes (AOPs) have been developed for the treatment of lignin from alfalfa black liquor digestion as discussed by the authors, which is based on the photodegradation of soluble lignIN using TiO2/UV photocatalytic technique.

TL;DR: A plausible reaction sequence for ONP mineralization on BDD anodes is proposed from anodic oxidation by-products, which follows a pseudo-first-order reaction.
