TL;DR: Generally, the performance of the catalysts was better when the pH of the feed solution was increased, and the highest residual phenol conversion was obtained for the ZnO-CuO, which was significantly higher than that obtained with the 10% CuO catalyst used as reference.

TL;DR: In this paper, catalytic wet-air oxidation of aqueous solutions (5 g · l−1) of car-ylic acids (formic, oxalic, and maleic) was carried out with air at 293-463 K on carbon-supported platinum catalysts.
Abstract: Catalytic wet-air oxidation (CWAO) of aqueous solutions (5 g · l−1) of car☐ylic acids (formic, oxalic, and maleic) was carried out with air at 293–463 K on carbon-supported platinum catalysts. Platinum was loaded on active charcoal by cationic exchange, then reduced under H2. Homogeneous dispersions of 1–2 nm metal particles were obtained. CWAO reactions were performed at 1 or 15 bar air pressure in stirred, batch reactors. Total conversion of formic and oxalic acids into carbon dioxide was obtained under very mild conditions (air at atmospheric pressure, 326 K). The Pt/C catalyst was almost inactive for the oxidation of acetic acid but maleic acid was oxidized under moderate conditions (15 bar of air pressure, 405 K) which indicates that the degradation of this acid does not occur via acetic acid.

TL;DR: In this paper, the concept of the mean oxidation number of organic carbon (MOC) was proposed to characterize real waste waters and sludges using physical, chemical or biological processes, and the applicability of the MOC concept is demonstrated using the wet oxidation of pyridine, stripping of toluene, decarboxylation of malonic acid, and dry oxidation of phenol as an example of a real system.

TL;DR: The results showed that electro-Fenton process can lead to 70 and 95% mineralization of the dye solution after 3 and 5h giving carboxylic acids and inorganic ions as final end-products before mineralization.
